Overview

The X-NUCLEO-EEPRMA2 is an expansion board designed for STM32 Nucleo developers to evaluate and test M24xx series I2C and M95xx series SPI EEPROM memory. It provides a hardware platform for verifying non-volatile data storage across different memory densities and bus protocols.

Why Choose This Part

The board features an Arduino UNO R3 connector layout for easy stacking on STM32 Nucleo-64 and Nucleo-144 development boards. It includes multiple onboard EEPROM ICs and an additional socket, allowing engineers to test various memory densities without custom PCB fabrication.

Applications

Industrial Sensor Logging
Testing data persistence and calibration parameter storage for industrial instrumentation designs.
Parameter Tuning
Developing firmware that requires frequent updates to configuration tables or user settings in non-volatile memory.
Bootloader Storage
Evaluating small-scale storage for secondary bootloader stages or recovery firmware images.
Protocol Comparison
Benchmarking communication overhead and power consumption differences between I2C and SPI memory interfaces.
