handwirehotswap VS mechware

I am trying to make my keyboards hotswappable without the need for PCB or complicated assembly. I found https://github.com/stingray127/handwirehotswap but the design can only work with 1 switch at a time, and I found that the solid core wires I got are pretty soft so the contact doesn't seem very robust.

I've had great succes with these: https://github.com/stingray127/handwirehotswap

Ooh ooh, I know something. I've been experimenting a lot myself lately. I've been socketing the MCU and have both Nice!nano and some other pro micros that I hotswap. Then I've been printing a bunch of these: https://github.com/stingray127/handwirehotswap to quickly rewire and move switches around.

3d printed from https://www.thingiverse.com/thing:4791318, the wiring detail is listed here: https://github.com/stingray127/handwirehotswap

I just did a Skeletyl with Nice!nano and very little soldering. Achieved this via these: https://github.com/stingray127/handwirehotswap

I built a 4x6 dactyl manuform this week using printed hotswap sockets from https://github.com/stingray127/handwirehotswap

Github, for extensive documentation on how to use it.

I do it for my keyboard firmware project, it's designed to compile up for Arduino (well, not their IDE, but VS with PlatformIO but it's much of a muchness) https://github.com/dairequinlan/mechware

code here https://github.com/dairequinlan/mechware/blob/main/src/input/MatrixInput.cpp That's dual use code, few #define chunks there for Ardiuno (Teensy) and Pico, but basically (using the more common Arduino syntax) ...

Plan is to add the BLE functionality as another pluggable module to my own firmware https://github.com/dairequinlan/mechware

Indeed. It makes for a neat µC for a keyboard, all that GPIO :-D OP are you planning a complete build ? This might be useful it's a complete pluggable and configurable firmware for PICO based keyboards. Dual compiles to Teensy/Arduino so there are a bunch of conditional blocks but it's fairly straightforward otherwise.

it's not an actual pro micro though, right ? It's a RP2040 board like the Pi Pico. I didn't know that that was even supported by QMK yet (if that's what you're trying to use). Coincidentally I just started using as a daily driver a custom split board I put together, which has a Pi PICO in either half, talking I2C to one another. Completely custom firmware though, source is here: https://github.com/dairequinlan/mechware/tree/pico
