Integration of Dronetag BS

Betaflight​

Dronetag BS can feed GPS data to the Betaflight flight control software through XBUS protocol, acting as a GPS module. Connecting Dronetag BS to the Spektrum telemetry receiver will enable you to access live positioning data.

Connect the flight controller with free UART port of the Flight controller.

Example:

4-pin Connector (Placed on Left Side)​

The connector placed on left side on Dronetag BS is a common JST SH 4-pin with UART interface with no flow control. This connector will be also used for support for Betaflight communication and Spektrum Telemetry XBUS in the future.
