## Features
- 51 keys "Split" keyboard layout. 36 finger buttons and 9 thumb buttons and 6 function buttons.
- Extreme low profile (only one pcb).
- Cost efficient solution with one pcb and one 3D printed cover.
- Function keys with total of three layer support (Primary + 2fn layers).
- Status indication -
- LED green = Normal mode
- LED green flashing = waiting for USB enumeration
- LED blue on = sticky lock initiated
- LED blue flashing = sticky lock activated
- LED red = error
- LED red flashing = Caps Lock activated
## Build environment rp2040 Zero
Rust embedded, rp2040 HAL
- Cargo (cargo.toml)
- rustup target add thumbv6m-none-eabi
- cargo install elf2uf2-rs --locked
- Flashing via rp2040 USB bootloader
- Pressing reset/boot button on rp2040 Zero board
- Pressing upper left corner on the keyboard when connecting the usb cable
## Hardware
[Schematics](eCAD/cmdr_mainboard_52_v1.pdf)
- 1x rp2040 Zero
- 45x Cherry MX compatible switches
- 6x Kailh Choc low profile switches
- 51x 1N4148 diodes
- 1x PCB [Gerber files](eCAD/cmdr_mainboard_51_gerber_v1.zip)
- 1x MCU cover (TBD)
- 1x 6x3 Cherry MX mounting jig (optional) [STL file](mCAD/cmdr_mounting_jig-MountingJig.stl)
