Not sure why no place on google or elsewhere here has this info easy to find... so I eventually found it here:-


Here is the connector pinout:

PinFunction
1RXD (UART receive)
2PACK- (GND)
3PACK- (GND)
4PACK+ (12.92V)
5PACK+ (12.92V)
6PACK+ (12.92V)
7PACK+ (12.92V)
8PACK- (GND)
9PACK- (GND)
10TXD (UART transmit)

As well as the meaning of all the pads on the back (not all board have these pads labelled - mine for example does not).

The SCL and SDA are especially useful - needed to reset the permeant failure flag using GitHub - o-gs/dji-firmware-tools: Tools for handling firmwares of DJI products, with focus on quadcopters.

As a matter of interest, has anyone tried the reset point to see whether it actually does reset the board.
It'd certainly be a bonus if it does, it could have a microswitch wired into it that can be fixed outside the case for future any future issues.

Can this tool be used to unlock the battery after replacing the cell?

So I need to solder to SCL and SDA test points so I can wire them to the CP2112? I tried this and could not get it to work. Not sure if I a) did not fully understand what you were saying b) i made a wiring error - i triple checked c) the battery/board are fried. Any advice?
