Adafruit KB2040 Kee Boar Driver - board with RP2040 microcontroller - Adafruit 5302

Adafruit Kee Boar Driver is a board based on RP2040 microcontroller. It has two ARM Cortex M0+ cores running at up to 133 MHz, 264 kB of RAM (no EEPROM) and an 8 MB SPI FLASH chip for storing files and CircuitPython / MicroPython code. Additionally, it allows external memory up to 16 MB to be connected via a dedicated QSPI bus. The small sized board has 20 GPIO pins (Including two on the QT port), a STEMMA QT connector and a USB Type C socket.
