Unfortunately my USB Micro connector is defective.
For what those connectors are? (see picture) https://drive.google.com/folderview?id=0B7_llVOMX6GVfkZPVVpveDZVelZjSm1KOTNTQ0NRR3VGUDZ0RHdDczZfQkJGeE1rZkE2dEk&usp=sharing
Can I connect an external power supply to this?
A voltage of 5 V I attach the left pin and the center pin
Greetings uzzoo
With battery door removed & looking into the back with the 3 pins in the bottom left the left most pin is +5v & right most pin is ground ...
It was used with the original htc car dock which had a rear cover that contacted those pins & would charge phone & detect in cradle & switch to car mode.
I tought those were for a second battery.... xD Nearly soldered one on there before i found this.
Do you know what the middle pin is responsible for?

O.K. Been a while since I have posted but here goes the new mod. I had wired in an old Ericsson car charger to the modded IPAQ connector to supply 5 volts to the XDA for power. Problem was I still had to use batteries or a seperate power supply for the GPS.
The cable that runs up to the GPS is a standard phone line RJ11 connector (3 wires). The GPS has a six wire RJ45 connector on the circuit board. What yo have to do is to replace the black wire (three 3 wires in it) with a four 4 wire phone cable. You will have on extra wire. We will use this for our power running up to the GPS. Connect this to the + 5 volt wire running in from the car charger. Connect the black to the ground and the green and yellow toio the data contacts on the PDA connector. Look at the two RJ11 jacks and use the correct wires. Now connect the black to the ground running in on the car charger.
Next unscrew the case on the gps. You will need to solder two jumper wires across from the RJ45 jack over to the standard power connector. Run a jumper from the - on the poer supply over to the pin that had the black wire connected to it through the RJ jack. Next run a jumper from the power jack + over to where the red power wire runs up providing 5v. Now it doesnt matter if you have batteries in it or not you will have power from the car charger being plugged in.
Will try to piost some pics.
Here is a link to the previous mod for the IPAQ cinnector.

Thanks for that, makes it a much more tidy job.
Hello everybody, I read in a few post some time ago that if I have a 1000mah car charger and i solder something inside it, ti ahould make the phone read that I'M CONNECTED TO a wall charger instead of a car charger, so I can charge up to 1a...now I can't find any pictures or tutorial regarding this procedure, maybe somebody can help me?
Thank you
Basically data- & data+ pins need to be bridged together
pins 2 3 in diagram (4 pin female A)
You can also just mod a lead if you do not want to dissemble the car charger.

thank you...what do you mean by: "You can also just mod a lead if you do not want to dissemble the car charger"
any pciture of a car charger modified?
thanks

bridge cable data pins rather than charger pins is what I meant.
I prefer internal mod of charge units. Some charge units have data pins soldered into board some don't, easier on those with data pins left loose & you can bend them closer together & bridge them together with just solder or if gap too large a bridging wire or off-cut from a resistor leg or similar ...
i didn't feel confindent modifying the charger so I modified the cable joining the green and the white cable. After a while it worked showing "charging AC" insted of USB. thank you!!
Has anyone probed the pins on the back of the watch? Mine didn't charge overnight and I'm stuck at work. I can build a custom cable but not sure what the pin order is.
I don't have the pinout, but I probed it with my meter and charging PINs are the first and the last.
With the USB connection facing away from you, the leftmost PIN is VDC (+5) and the rightmost is GND.
To rephrase that because you don't have the cradle: with the watch laying on the watchface and the crown facing towards you, the leftmost pin is GND and the rightmost is +5V.

My 6yr old lost my charger and i was lost today without my watch.
Got 2 new chargers ordered (one extra just in case) but till they get here I was stressed over not having my watch.
With the info from this thread I took an old phone charger and cut off the mini usb end and stripped the two wires and taped then clamped onto the appropriate pins of my Urbane with a paper clamp, it is currently charging and I am once again a happy camper.
Thanks!
hi,
could you please also post the pin for the data connection. my cradle can charge, but cannot connect to PC. I wonder its the cradle problem.
thanks!
Last night my cord got broken.
I repaired it and it was going so well.
Until I accidentally pulled the ground wire from plug
It didn't charge but when I connect the ground wire (the ground wire near the usb plug...the other side, I mean the usb was cutted so it has two sides. The side with the usb plug and the side with plug that connects the tab. I accidentally pulled the ground wire on the side of that connects the tab) to the data wire, it indicate that it charges but always 0%.
I left my tab to charge overnight(still indicating that it's charging) and when I tried to turn it on. It won't
So basically. The illustration is like this (underscores are for spacing)

Tablet <PLUG--[-]----------------------[-] USB Male Connector> Computer

I'm just curious, what could have possible happened?
The device is GT-P3100 or Samsung Galaxy Tab 2 7.0
Does anybody know what is the pinout of pogo pin connector of Tab Active2? Samsung itself does not provide much accesories so I'm quite conviced that it should be somewhere revealed.
A few months on - have you made any progress? I'm looking for the same.
The most I've discovered so far is that the power comes in through two of the three centre pins.
There's a post with a photo on another online forum : https://advrider.com/f/threads/ultr...hones-my-guide.1206076/page-115#post-36686010
pinout
pin 1 idk
pin 2 idk
pin 3 ground
pin 4 v in (idk voltage)
pin 5 ground
pin 6 idk
pin 7 idk
i thought it might be normal usb 2.0 (something like +, -, ground, v, -, +) but idk only pins which aren't open lines with the usb port (only ones where the multimeter beeps in diode mode) is ground (pin 3 and 5) i know about the volt pin from a picture of a charging dock (edit: oh i forgot, that ^ picture)
i expect that pin 4 is just 5v in, but idk. if you find out more, please let me know
I got my hands on a Galaxy Tab Active 2/3-charging dock (made by Brodit) yesterday. It's only equipped with the center three-pin-connector, has a short tail of cable with a 6-pin-connector (looks a bit like the one for PCIe grapics cards but only three pins are used) and comes with a suitable car power adapter.
I first opened up the car adapter, since I've anyway planned to user an wall adapter.
It has a three pin output:
yellow (thin): marked as "FB" (Feedback?)
red: Vout
black GND
The rating on the car adapter said 5VDC 3A
I connected my scope to FB and checked if there happens some sort of feedback, but nothing between 1s/div and 1µs/div): FB was simply high/5V as soon as the adapter got powered and all cables were connected, wheter the tablet was in the dock or not. So, probably not pogo-pin-relevant, although i guessed for something like charge speed detection, powering off the charger if no tablet is connected or cycling the charger off and on according to the charge level. Nope.
Checking the wiring bewteen charger and dock-pins by multimeter in diode-mode releaved the magic:
pin 3 GND
pin 4 Vout(5VDC) +FB
pin 5 GND
Since it seems to be all about symmetrics, for those who are interested in establishing a data connection it would probably an idea to guess something like
Spoiler: this
1 d-
2 d+
3 gnd
4 5VDC
5 gnd
6 d+
7 d-
?
If anyone needs further investigation on the dock or original charger, please feel free to ask!

I know this is an old thread but did you ever create your own charger dock with this info?

No, I use the Brodit 513697 dock. The pogo pin-out for GND and +5V is confirmed though, so if you're good at 3D modelling and printing and can fit small spring pins, you can certainly build your own charging dock.
