nRFMicro - a Pro Micro alternative for wireless keyboards
I'm not into wireless keyboards, but still love the idea: a split keyboard without wires between the two halves or the master and the PC.
Designed and built by Joric in KiCad and fully autorouted with Freerouting, the nRFMicro is just the perfect Pro Micro drop-in replacement for wireless boards.
Same size as a Pro Micro (18x33mm), has both MicroUSB and Type-C, Li-Po charger and BT 5.0.
Runs full-featured QMK software (nrf52 fork), uses USB Mass Storage for firmware updates.
Runs fully wireless split keyboards over Bluetooth, does NOT need TRRS cables or receivers.
Supports wired split keyboards via USB-C, MicroUSB and I2C/Serial extension cables.
The nRFMicro project is well documented, you can find all the necessary info to build and use one on the project's git.
For other common controllers or for a way to upgrade your Pro Micro see my related guides.
