So I was attempting to replace my stock 9X gimbals with taranis gimbals and in trying to remove the old gimbal wires from horizontal trim PCB, I believe I fried the trim PCB through extremely poor soldering (or desoldering) skills.
One of the new gimbals works fine, but I get no response whatsoever when I install the other new gimbal. I tried replacing with the stock gimbal and still get no response from the sticks, but the trim buttons do still function.
My question: assuming there's no way to repair this board (by ordinary human means), is there a place to procure a replacement horizontal trim PCB? Any suggestions are appreciated.
Fried 9X horizontal trim PCB
Re: Fried 9X horizontal trim PCB
Had a thought overnight:
Assuming the board is toast and there's no way to get another trim board, could I directly solder the output wires from the gimbal pits to the input wires coming from the board? Easy enough to get the pos & Neg wires figured out, but I'd need to figure out which of the remaining 4 wires transmit which signal. I don't think a multimeter would help on this one, as the board is fried. Anyone know the pinout of this board offhand?

Re: Fried 9X horizontal trim PCB
You may have broken some tracks on the board. It is difficult to be sure with all the flux residue. It is worth trying to clean this off, I usually use some cellulose thinners on a "cotton bud".
The connections should be:
Blue wire - Analog VCC
Green wire - vertical stick signal
Yellow wire - horizontal stick signal
Orange wire - Analog ground.
Worth checking with a multi meter you see 3.3V between the orange wire and the blue wire.

The difficult we do immediately,
The impossible takes a little longer!

Re: Fried 9X horizontal trim PCB
I was able to get a multimeter and determine that my signal and ground were good, but Vcc was not working, so I soldered the red wires from the taranis gimbal directly to the blue cable/pin and all is working as it should!
Thanks for the help Mike!
