Microcontrollers often contain EEPROM or app-writeable FLASH memory for saving persistent values which will remain stored after an off-on power cycle. However, these often suffer from small storage space and can be destroyed by only a few thousand erase/write cycles. The neoPLC RAM board solves both these problems by providing 256 kByte additional storage space that can be written to 4 million times before fatiguing. This board offers a low-cost alternative to SD Cards in a smaller package but with much less memory. The neoPLC RAM board is good for data-logging but does not have sufficient memory to store large files like pictures or video.

SPECS: 2 Mbit (256Kbyte) EEPROM, up to 1 MHz i2c, 4M write cycles at room temperature, 100 years data retention.
