nRF

nRF is a line of MCUs from Nordic Semiconductor, popular due to the integrated Bluetooth radio. OpenDeck currently supports just nRF52840 MCU based on 32-bit ARM architecture. This MCU doesn't have integrated EEPROM - instead, EEPROM emulation is used within their flash memory for storage of various configuration options.
