The X-NUCLEO-EEPRMA1 expansion board is designed for M24xx series I²C and M95xx series SPI EEPROM for data reading and writing.
The expansion board acts as an external storage device that can be used to store data such as manufacturing traceability, calibration, user setting, error flags, data log and monitoring data to make applications more flexible and accurate.
The X-NUCLEO-EEPRMA1 expansion board is compatible with the Arduino UNO R3 connector pin assignment and can be easily plugged to any STM32 Nucleo development board. You can mount the ST morpho connectors if required.
