# pica40
![pica40](https://i.imgur.com/CKImjAPh.jpg)
A family of 40-key split ortholinear keyboards with rotary encoder.
- Keyboard Maintainer: [zzeneg](https://github.com/zzeneg)
- Hardware Supported: Pica40 PCBs, Pro Micro (rev1), XIAO RP2040/nRF52840 (rev2)
- Hardware Availability: [GitHub](https://github.com/zzeneg/pica40)
Make example for this keyboard (after setting up your build environment):
make pica40:default
make pica40/rev1:default
Flashing example for this keyboard:
make pica40:default:flash
make pica40/rev1:default:flash
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
## Bootloader
Enter the bootloader in 3 ways:
- **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
- **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
- **Keycode in layout**: Press the key mapped to `RESET` if it is available
