Adafruit Feather M0 - permanent memory

Post by idarlund »

Hi,

Hi,

I can see that the Adafruit Feather M0 RFM96 LoRa Radio - 433MHz - RadioFruit (https://www.adafruit.com/product/3179) does not have an EEPROM. Does it have some other form of permanent memory which can hold variables if it looses power? Maybe as an add-on?

There are some libraries that let you treat some flash like EEPROM, and there are external FRAM boards. E.g. https://learn.adafruit.com/adafruit-spi-fram-breakout (it has C++ and Circuitpython support). If you are using C++, check out https://www.arduino.cc/reference/en/lib ... shstorage/. I'm unsure of a CircuitPython solution.

Thanks for your answer on this thread as well! I guess I'll go for the SPI addon for this project :)
