New version not powering up via battery #14

Closed russrussw closed 1 year ago

russrussw commented 1 year ago

I have the latest board version V1.1 of date 2022-5-22 which will NOT power up using the battery switch. I have 30 of these boards :-( Battery fully charged at 4.12v however boards seems to work using usb. Although some issue with modem turning on then off again.

I discovered this board does no longer have a LED you can program unlike previous versions. So when powering up via battery no lights go on at all, making it seem as though it is OFF. Unless you plug a solar cell on the solar input.

Hello, Please refer to the sketch. To use batteries, you need to enable IO12 (see schematic diagram).
