BetaFPV FC power issue


#1

Hello everyone,

I have a BetaFPV OSD FC that has been working brilliantly for a while, but recently it’s half dead (!?).

The FC will not arm or receive any commands from the Tx unless powered by the USB.

I can spin motors, arm, change flight modes everything while the fc is plugged into the USB (and battery). But if powered just by battery it’s unresponsive to any Tx commands.

Any ideas ?
