📄️ Keyboard Firmware
The keyboard firmware is a fork of i2cpuppet with a few additional features to support the Beepberry.
📄️ Power Management & Battery
The onboard RP2040 controls the power to the Pi, as well as measuring the battery level with its ADC. The Beepberry can be safely shutdown by holding the "End Call" button on the keyboard.
📄️ RGB LED
The RGB LED is connected to the RP2040, and can be controlled by the Pi via i2c by writing to specific registers.
