This is a custom layout for my wireless split Redox keyboard.
My OS is set to neo2. There are layers to type neo2 when OS is set differently.
See config/redox.keymap for details.

I'm using nRFMicro 1.3.
Firmware files are available for 90 days as action artifacts.
Connect a cable, put both halves into bootloader mode and copy the uf2 files to MSD.
When just updating keymaps only the left half needs to be reflashed.
