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.

Betaflight Flight Controller integration
Connect the flight controller with free UART port of the Flight controller.
Example:
Follow the wiring diagram for BS 4-pin Connector below. Be extra careful to avoid connecting VCC and GND to the module them reversing will permanently damage the module.
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.

Pin # | Name | Scheme Color | Description |
---|---|---|---|
1 | VCC | Red | 3.3V to 17V. Directly connected to pin 1 at 3-pin connector |
2 | UART RX | Green | Receive of the Dronetag device (3.3V logic - 5V tolerant) |
3 | UART TX | Blue | Transmit of the Dronetag device (3.3V logic - 5V tolerant) |
4 | Ground | Black | Ground connection |
VCC pin 1 directly interconnected with VCC pin 1 at 3-pin JST SH (the other connector)
