Overview
DarwinFPV Anti-Interference Drone GPS (GM8) is a Drone GPS module based on an aerial-drone GPS hardware solution, using multi-frequency strong interference elimination technology and multipath signal detection and elimination technology for more stable and reliable positioning. Its communication protocol is modified to be compatible with BetaFlight, making it suitable for FPV drones that require stable GPS performance.
Key Features
- Multi-frequency strong interference elimination technology and multipath signal detection and elimination technology for improved stability
- High-gain, omnidirectional patch antenna for more stable signal reception
- BetaFlight-compatible communication protocol (UBLOX)
- Supports GPS/GLONASS

Setup Notes (BetaFlight / INAV)
- Use a 5V power supply for the GPS module.
- TX and RX must be cross-connected between the GPS and the flight controller (GPS TX to FC RX, GPS RX to FC TX).
- In BetaFlight Configurator / INAV Configurator, enable GPS on the selected serial port (example shown: TX2/RX2) and set baud rate to 115200.
- Select UBLOX as the GPS protocol.
- Turn off automatic baud rate and automatic settings if the flight controller cannot recognize GPS (noted for BetaFlight 4.3.0 firmware or above).
- Do not search for GPS positioning satellites indoors; test outdoors in an open area.
