QMK usb-usb converter
Hi everyone!
I’ve been working on a small project: a USB-to-USB converter for QMK. The goal is to allow more flexible connectivity for custom setups.
The core logic is based on the work by sekigon. I’ve implemented some modifications to make it work specifically for USB-to-USB bridging.
If there is enough interest in this, I’m share the source code and the assembly schematics with the community.
Let me know what you think in the comments!
Update. I worked on this project a long time ago, so it's currently running QMK version 0.22. The kit includes an RP2040-zero chip, an OLED display, and a buzzer. It costs less than $10. All the main QMK features work.
Update2. I’ve made the repository public. I haven’t prepared the hardware assembly instructions yet, but that shouldn’t be a problem for those in the know. https://github.com/DmitryMarugin/rp2040.git
