The RAK15000 WisBlock EEPROM Module extends WisBlock systems with reliable, low-power non-volatile memory based on the Microchip AT24CM02 chip.
 
With 2 Mbit (262,144 × 8 bit) of storage and I²C interface compatibility, it allows devices to store calibration data, configuration settings, or logs securely, even when power is lost.
 
Optimised for low energy use, the module’s standby current is below 3 µA, making it ideal for battery-powered IoT applications. Its built-in error correction ensures data integrity over time, while the WisBlock Core can control power to further minimise consumption.
 
Compact, efficient, and reliable, the RAK15000 is a practical choice for designs that need persistent, secure data storage.
