The X-NUCLEO-EEPRMA2 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 settings, error flags, data logs and monitoring data to make applications more flexible and accurate.

The X-NUCLEO-EEPRMA2 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.

Key features
  • Up to 1-Mbit serial I²C bus embedded EEPROM
  • Up to 4-Mbit SPI bus embedded EEPROM
  • Easy portability across different MCU families
  • Equipped with Arduino™ UNO R3 connector
  • Compatible with STM32 Nucleo boards
  • Free comprehensive development firmware library and sample implementation available when the X-NUCLEO-EEPRMA2 expansion board is plugged on top of a NUCLEO-F401RE or NUCLEO-L053R8 development board
  • Developer can choose and solder an EEPROM to be tested using the evaluation software provided
