The nullbits Bit-C PRO Board is based on the Raspberry Pi RP2040, and comes in the Arduino Pro Micro footprint.
The board module contains definitions for the onboard RGB LED.
Example:
>>> import board
>>> board.led_red.on()
>>> board.led_green.on()
>>> board.led_blue.on()
To get the board in bootloader mode ready for the firmware update, execute
machine.bootloader() at the MicroPython REPL. Alternatively, hold
down the BOOTSEL button while plugging the board into USB. The uf2 file below
should then be copied to the USB mass storage device that appears. Once
programming of the new firmware is complete the device will automatically reset
and be ready for use.
These are automatic builds of the development branch for the next release.
