SpeedyBee BetaFlight Bluetooth USB Adapter
The SpeedyBee BetaFlight bluetooth USB adapter allows you to access betaflight on your phone without the need of a computer.
Simply download the SpeedyBee App, plug in the USB adapter, plug in the battery and access BetaFlight on your phone.
The SpeedyBee does not power the VTX so it’s safe to use in the pit. You can change the VTX channel/band/power from the app.
