## Kern Project

This enclosure was designed for the [Kern](https://github.com/odudex/Kern) project, which uses the ESP32-P4 as an air-gapped Bitcoin signer. Kern supports the 4.3" Waveshare board as the wave_43 target. You can find build and flashing instructions in the [Kern README](https://github.com/odudex/Kern).
