[rev2.0WHS] Not Working - Receiver and Right Hand Transmitter Soldered

aliasboink commented 2 months ago

Hello,

I am rather new to soldering on PCB's and flashing firmware. I have done the following:

I have soldered the transmitter and the right hand transmitter.
I have flashed the QMK firmware on Arduino (2 Pro Micro 5V Arduinos, tested with both).
I have flashed the firmware on the transmitter and the receiver using the docker compose setup.
Once the transmitter is plugged in, only the Arduino green LED lights up.

Currently no key presses work on the keyboard. I have checked the connections with a multimeter and currently I am at a loss.

Can the firmware flash without the YJ-14015 module being soldered on properly? How could I proceed with troubleshooting from this point onward?

Edit: I've ditched the initial right hand PCB altogether and soldered a new one. Here is a GitHub repository with pictures of all the components: https://github.com/aliasboink/rev2.0WHS_pictures

The columns all have roughly 3V. The rows all basically ground (pull down resistor I presume?). Every column goes to 0 upon a keypress, specifically testing with K35 in my case for the most apart. Any idea what could be the issue?

Do you happen to have stable power source (i.e new batteries)? Lately the YJ-14015 modules are power-hungry.

Yep, using new batteries, they measure 3V.
