rtc ds3031 3.3V write protection
Kaspar.Schwarzenbach 2025-10-25 13:43:23 65 Views1 Replies I run a rtc clock ds3031 breakout module (dfr 0998) on an arduino nano 33 IoT (samd21 architecture) at 3.3 V.
But I can’t write and store the actual date and time!
How to overcome write protection on an ds3031 rtc module?
btw: uploading a 3 kb file here throws an error «max 10 MB» = ?
