Hi everyone! I’m having a problem with the RV3028 board (I’m using it connected to a Raspberry Pi Pico with MicroPython). Basically, when I remove power (I checked and the supercap is charged — I left it charging for weeks), I lose the set date/time after just a few hours. In the product description you write: “When connected to power, the RTC trickle-charges the supercap in just a few minutes - enough to keep the clock going for a couple of weeks once power is removed”, but unfortunately after a few hours I lose the date/time I set. It’s as if the switch-over to the supercap isn’t happening. Do I need to set something at the RV3028 EEPROM level? What am I doing wrong?

Hi Fred,
Welcome to the forum!
Sorry to hear the RTC is losing time.
Could you please send through a photo of your setup? And the code you are using?
The switchover ought to be set up in the driver codes init.
I cant imagine you have done anything wrong, maybe just skipped a step in the setup - regardless, we’ll figure out whats wrong and solve the issue!
