Support for the BBC micro:bit v2.
The micro:bit v2 was designed by the BBC and released in 2020.
The board is based on the Nordic nRF52833 SoC, featuring 128KiB of RAM, 512KiB of ROM, and a 2.4GHz radio, that supports Bluetooth Low Energy (BLE), 802.15.4 as well as a Nordic proprietary radio mode.
Additionally the boards features 2 buttons, a 5x5 LED matrix, a speaker, a microphone, an accelerometer and a magnetometer.
The board can be flashed using OpenOCD and PyOCD. Debugger is also available with both programmers.
The programmer chip provides access to STDIO via USB. On Linux, stdio is usually available on /dev/ttyACM0. Use the
term target to access stdio:
The 5x5 LED matrix display can be driven using the Common microbit LED handling.
The Microbit logo and the rings are configured in resistive mode, and expressed as buttons by default when SAUL is enabled (through saul_gpio_params_t). Note that to press them, you have to touch the GND pin at the same time, and may need to press hard if you have dry fingers. See the micro:bit documentation on touch for more information. Capacitive mode is currently not supported.
