  • What is the purpose of the built in jumper between USB_VCC and RAW? If you plug in a battery, then turn the power switch to on, then plug in a USB cable, 5 volts is dumped onto the battery through F1. My Lipo got to 4.5 volts and started to get warm before I noticed this.

No public wish lists :(
