“The module looks well made. I haven't actually tested it yet but I can't see why it wouldn't work. It came with a battery installed although it seemed to be an old one. Perhaps used for testing and left in there? One odd feature is the 470K series resistor in line with the battery. Technical support is via a forum that doesn't appear to get much attention from Pimoroni staff. It would be nice if schematics were available and there was more active support available.”
“Nice little RTC breakout board. I began playing around. I use it with MicroPython and can for now set time/date and reread after a moment. I use it with a Pico connected via USB to a Raspberry Pi 4 and program with Thonny IDE.”
