[Q] Pogo pins on the side, what are they for?

Any clue what kind of device\dock the galaxy nexus will be able to connect to with those three metal connectors on the side of the phone?

a desktop dock was shown in the presentation last night.
eric b

Its mainly for charging isn't it?

Probably the dock have MicroUSB, Audio 3.5", and HDMI output.

hum with the all in one os I hope this means that docking your galaxy nexus to a tv makes it run like a google tv and that we can get a padphone-like accessory. One of the tings I love about android is there is virtually no reason for me to dock my phone to my computer, I can do 99% of the things I want over data, wifi or bluetooth (most of it without any need for me to interact with the device)... it would be a shame if they put those pins there just for that.

The Pogo Pins are for a Docking Station.

I hope there's Car dock as well as the Pogo desk dock - just like the Nexus One.

only problem is... that in the presentation it docked on the hand side of the phone. But the pogo connections are shown to be on the right hand side of the phone where the power button is.

What the hell is going on there? I'm figuring the dock at the time of launch was fictional and 3d generated and they overlooked this mistake.
As it stands having the pogo connection points on the right hand side is kind of dumb, as it orientates the device in landscape in the opposite direction to pretty much every single other landscape dock on the market.
Not only that if the phone does dock on the right hand side it will cover up the power button, which in most android phones is what powers up the touch screen. So they must have a solution there, I imagine it will just mean the screen will never turn off.
Really hope they sort this out properly, as this is why i have hung on to my N1 for so long, and I've been hang out for a next gen, 'wireless' charged phone.

SCOOP: the real galaxy DOCK
here it is people.
I am convinced this is it. Pogo pins and the notch out for the power button. Its exactly like in the Galaxy launch, but minus the dodgy 3D/photoshop render. It now docks on the right hand side, as expected from the placement of the pogo plugs.

Hi
Where I can bay this dock any idea in uk??

Nowhere officially yet. Give it another week or two.
Sent from my samsung gt i9250 which is in the wrong country.

Do we have any information on the pogo pin outs, if the system is intelligent or dumb. The images appear to show that the pogo pin car down handles charging and audio out?
Eg - I want to look into a DIY solution.

Pogo pins.

Not Internet-coined. POGO is a trademark used since 1965.

Nice article with 99% irrelevant information. Thanks.
When were these connectors officially called pogo pins? Did I miss something or are we assuming that's what they should be labeled as?

The three pins on the phone...

What's the three "pins", dots or whatever you want to call it on the right side of the phone, what does it do? Is it like a dock station or something?

They are supposed to be used in conjunction with a car dock or desk dock to leave the end of the phone open (Think about our phones in a dock, sideways, in your car being plugged into the charging port) the problem is, is that Samsung doesn't see enough customer want and therefor is not currently planning on making said accessories.

Could have something to do with the extortionate prices they wanted for them.
£49.99 for a dock? I expect at least a spare charger to come with it. However, this was not to be the case.
£49.99 for a piece of shaped plastic, with some die-cast weights inside, and 3 copper charging connectors. That's value for you

If it makes you feel better, the US version for Verizon is $49.99 but doesn't use said connectors, it's just a piece of cheap plastic with holes for cables.

Look up the nexus one car and desk dock to see. That phone had the same 3 docking pins.
It sucks that we just recently found out that samsung cancelled production for these though...

That sucks. Wanted to buy both.

I was just wondering if I could ask a potentially naive but somewhat related question.
How do the three pins work? I'm assuming you'd need to use two for charging (+ve and -ve)? How do get everything else through just one pin? Have I got the wrong end of the stick?
Thanks, Rowan.

They would sell so many more accessories if they didn't try and pork people do bad.

Samsung canceled the car dock?
God I hope Motorola makes the next Nexus. Samsung is the worst.

Lol, great idea to combine 2 technologies

the outer pins are for charging the inner pin is for grounding i believe, i don't think it has audio capabilities

What are you using for your pogo pin contacts?

Happened to come across this business card holder in the store and it holds the Galaxy Nexus perfectly. The mesh spacing is also almost the same width as the pogo connections, so I'm looking into modding this into a pogo dock.
http://www.officemax.com/office-furniture/desk-accessories-organizers/product-prod2980161
Just wondering what everyone has been using for their pogo pin contacts? I've seen mentions of guitar string, push pins, and screws from other threads here. I plan to solder the ends of the USB wires to the contact, then hot glue them in place on the holder (which also will insulate them from the mesh so I don't get any shorts).
I'm also thinking of making a slightly raised section on the right side that lines up with the power button so that I can push the phone down slightly to hit power, since I don't want the screen on constantly while in the dock.

you might want to check here for info on enabling the middle pin to get AC charge and Desk/Car mode.
As for docks, I'm using a case, so i'm going to start work this week on moding my case to make pins accessible from the outside.

Pogo pins from yokowo, lined up with the official stand/extra battery charger.

Is there anyway to get these in the US? I'm not near their 2 stores here and I don't see anything about ordering online. I'd prefer to use something like this that's actually made for it rather than have to ghetto rig something

I think ghetto rigging something is the only way to go with the pogo contacts. There arent many accessories that make use of the contacts and dont think Samsung or anyone else is going to be coming out with anything new as newer phones come out. I hope as it seems like it is an awesome way to charge the device but think you have to check out the DIY sticky thread at the top of this forum to get better ideas. GL

Who's Interested in a Auto Dock?

I'm designing a dock for the N7v2 for use in a car. It will have Qi wireless charging and Bluetooth audio receiver, with a standard 3.5mm audio output. It should be compatible with most cases.
I am also currently designing a mounting method that should be close to universal between different cars, and should not fall off like most other docks in the market.
I designed one for the N7v1 using the Pogo pins, and I can never go back to not having a dock for my tablet in my car. It's amazing the difference it made for me.
I want to know a couple things.Please reply with the following template:
1. Would you want a dock like this?
2. How much do you expect to pay for it?
Thank you everyone, in advance!

Sounds like a great idea. Do you have any links showing your work with N7v1? Heck, I may be interested in that version since the v1 tablet can be had for cheap these days and is more than capable for the limited functions needed in a car. At any rate:
1. yes, would be interested
2. no idea what a fair price would be, but $50-$100 seems like a fair ballpark

I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?
The wireless car mount/charger iterations for the Nexus 4 were a failure, I recall.

I've attached 4 pictures of the dock I made for the first Nexus 7. You'll notice that it inst exactly a dock you can put in just any car. I realized I made a little too rugged... and big!

Well, that's why I don't leave the tablet in the car, I keep it with me. While I'm in the car, if it's hot out I will have the A/C on anyways, so heat has not been an issue.
Most of my broken devices are dead because the USB port broke because of wear and tear. One of the points of this dock is to reduce that. Plugging in a device everytime I get in the car is partly to blame for such failures. I would have used Pogo Pins, like with the first Nexus 7, but they don't exist on the second.

Hey everyone,
my name is joseph and i am new to this website. I am also new to the whole rooting phones as well as i am learning the basics of computer science-- os, rom, ram, eprom, android, custom roms.....etc.
I honestly have no idea what i am looking to read and study up on so if you have any ideas than please let me know so i can educate myself. I end goal is to be a program developer.
Also i have an amazing ideas of a great new app. I have the layouts for the app but don't have the knowledge to build the app myself. If you are interested in learning more about my idea and possibly collaberate pleae let me know and we can possibly exchange numbers.
Another thing, i am an inventor and creator.

Look at active Brodit car mounts - say for a Nexus 4. There the device is supported and aligned as it glides onto or off the USB. There is no possibility of twisting or yawing.
I think your proposal maybe over-kill - simplest solutions are always best IMHO. A guy in the Nexus 4 forum came to no good end and had a lot of unhappy 'subscribers'. Just saying.

I would normally agree. I was hoping to make one that doesnt require a case to be removed to use. I designed my previous dock the way you describe (except it used the Pogo pins on the side), but I always had to remove the case and eventually the first case was showing signs of damage from being removed so often.
My hope is that the base platform of the dock I want to build will be compatible with multiple models of smartphones and tablets that are Qi capable. That'll require a lot more planning, but may be worth it.

Well if you're set on the route you've described; ... I see you've picked up on the Peltier pump in another thread. Credit me somewhere if you make it!
But I might consider an approach made by Philips in an Android Bluetooth Speaker and dock. The adjustment for USB and its placement on an edge, plus 180 degree rotation needed for some models, was catered for physically. A much cheaper approach which copes with tablets and phones!

I think I will use a Peltier pump. And yes, I'll make sure you get credit for that idea I'll mount the transmitting coil onto the cold side (probably with a layer of copper in between, we'll try several things) and have the hot side of the pump mounted to the aluminum/sheet metal of the back plate (probably with thermal paste as well). I'll have the pump on a simple thermostat. Good thing I have an EE helping me with this project
Hopefully the final product won't need a Peltier pump, but I will definitely have it in the prototype.

I haven't had very good experiences with using that type of dock The results of daily use tend to be USB ports that are stretched and loose. At least that's how it has been in my experience.

Don't forget to talk to your EE about eddy current loses in any conductors (copper, aluminium) you have nearby to your induction coil.

Interesting read, but with the cooler this is going to be a very expensive dock. Without it, look to Canada for your market.
I rigged up one for my Nexus 4 last Winter. Based on some testing, I used the most efficient charger I could find for that phone (the LG wcp-700). It worked very well... until late spring when the mercury broke 70. To make a long story short, I pulled it last month as the phone was getting too hot. This in a suv with a 4 liter v6 with plenty of air conditioning, front and rear.
Without the cooler, the tablet needs to be located directly in front of a vent, or even in moderate climates the unit will get hot enough to significantly reduce charging current.
One more thing to consider... the Nexus 7 is polarized vertically. This means that it is invisible in landscape orientation for anyone wearing polarized driving glasses, which I am willing to bet is a large percentage of your prospective market (tech savvy, auto enthusiasts). Most displays designed for vehicles are polarized at 45°, making this not such an issue.
While the tinkerer, software developer, and electronic geek in me wanted a fully integrated tablet in my truck, I soon came to the conclusion that it was simply not practical. What is really needed is a properly done appRadio, where a head unit can mirror the display of a mobile device (ideally wirelessly - miracast, etc.) with a control link set up to pass touches on the head unit back to the mobile device. We're about 30% there now, but a lack of standards, and major players wanting proprietary solutions is a problem.
I wish you much success with your endeavor, but just wanted to share my experience and feelings that this will not be all that marketable a product.

The problems you had with the nexus 4 does not necessarily effect the nexus 7. The nexus 4 was pretty terrible at wireless charging. I had a car setup with a qi charger with the lumia 920 and it worked great even in hot weather. I am not saying the nexus 7 will work, but it might.

What makes you say that? I ask as I have seen relatively similar performance with both the N7 and N4. The tricky thing about the N4 is that the coil is not centered in the vertical dimension, so for folks making the assumption that it is, there will be quite a bit of offset.

I say that because of all the issues people had with car docks. It also had issues with the dt-900 qi chargers when it shouldn't have. It heated up excessively with most chargers.

I wonder if there will be an Official dock that lets you:
1. Charge
2. Expand TV HDMI out
3. USB port for Hard drive access
I really want the Nexus & FHD to be a Home entertainment player...may be a remote/ Or Kinect like gesture control app built in with the dock
Hope this comes true...it will be the best Combo for a home unit!

3D Printed Galaxy Nexus Pogo Pin Dock

Hello guys,
I was recently looking into upgrading my maguro phone and decided to install CM11. I fell in love with it all over again ! Since I already had the car dock I decided to get the desktop dock too but it seems like it's very hard to come by one of those. I decided to make my own.
Currently the 3D model is rough but I got the phone to fit perfectly.
Do you guys have any suggestions (Hardware or software) for the dock?
NOTE: Implementing audio out is not on my list!
Features I want to have
1) Detect computer USB (500mA) vs dedicated micro USB chargers(1A)
2) Measure input voltage on the charge input
3) Measure current going in the phone (maybe...)
What are your thoughts / opinions?

Wow, that CAD model looks great! Which software did you use to make that? SolidWorks? =P
Anyway, you can look up circuits to do the monitoring for #2 and #3. For components, digikey.com is your friend (or Sparkfun for more hobbyist stuff). I'm not sure what you mean about #1 though.
EDIT: If you don't mind, please release the model (raw CAD files or STL) somewhere (thingyverse? here?), so that others can use it. That's the point of 3D printing, isn't it?
EDIT2: I think I know what you mean by #1 now. I don't think pogo pin charging can go any faster than 500mA though, if I remember correctly. Something to do with the phone's internal charging circuit... check that.

Once it's done I will post the STL etc. It's done using SolidWorks yeah it's a very neat application !
I doubt I will have any issues with the circuits. I will most likely make my own. Then after that..software.. Good reason to learn MSP430s as well.
regarding #1. I had the understanding that the phone can charge with 500mA current limit or 1A current limit. Once i get the software going I will see if it can change with 1A.

I dug around a bit and I didn't see any clear oscilloscope captures of the signaling pin. I don't have the software working yet so this is just the phone "probing the pin". No one is talking back.
Yellow trace is the +5V input. "Blue" trace is the ID pin.
It seems like the pulse should be 100ms but I am measuring 110ms. No big deal.
A huge thank you goes to the guys from this thread for doing all the hard work !
http://forum.xda-developers.com/galaxy-nexus/accessories/pogo-pin-dock-t1614287

These are scope captures of the Car dock.
Everything seems to align,
100ms wake pulse from phone
100ms wait time.
100ms dock type (car)
50ms charge type (charger)
100ms audio (no audio)
NOTE: The voltage levels are very funky. I attribute that to the worn contacts on the pogo pins and my uber crappy test setup when I was measuring this. Once I have my circuit, I expect them to be in the 1.8V range. I am not worried right now at all.
