STMicroelectronics X-NUCLEO-PGEEZ1 EEPROM Memory Expansion Board is designed for the M95P32 series SPI page EEPROM for data reading and writing. The board allows the evaluation of a new memory page EEPROM through a single/dual/quad SPI interface. The X-NUCLEO-PGEEZ1 acts as an external storage device that can store data, such as manufacturing traceability, calibration, user settings, error flags, data logs, and monitoring data, to build more flexible and accurate applications. STMicroelectronics X-NUCLEO-PGEEZ1 expansion board can be plugged on top of an STM32 Nucleo-144 (via ZIO connectors) or STM32 Nucleo-64 (via Arduino® UNO R3 connectors).
