The board was created by SparkFun, equipped with additional CAT24C512 EEPROM memory. The board with 512 kb of EEPROM can be used with modules that do not have built-in RAM, such as SAMD21 chips. The module with EEPROM can store GPS data and user settings that must be stored between sketch uploads. The module uses the I2C interface for communication via the Qwiic connector or the leads on the board.
