Great use for an old broken Flight Controller - UART, ExpressLRS, GPS Troubleshooting and firmware

CORRECTION: I connected the Blue and White Wires to RX2 and TX2 (not RX1)

If you have an old flight controller sitting around it can be used for it's UARTs for updating firmware and testing sensors.

I have used it for Betaflight passthrough firmware updating my ExpressLRS receiver that I use on my Arduplane build and testing a GPS. I'm sure I'll use it for a lot more in the future.

I plan on connecting small alligator clips so I don't have to solder the wires in the future.
