Hello community. just received a kwikstik-40 and am unable to charge the battery via USB. It powers up and runs while connected to USB but even after 5 hours it only shows 1 bar of charge and not enough to power up on the battery.
As you can find, there is a ON/OFF switch on another side of Kwikstik_K40. Did you turn it on when you want to use this board?
If yes, there is still no 3.3V power. I think you need to check if battery still has energy.
Hope my reply can help you. Thanks.
