Structure and Wiring Instructions
Usage Requirements
- 1. Connect TX, RX, and GND to the flight controller, and provide a separate 5V power supply to the module.
- 2. Open-source flight controller parameter settings: GPS_TYPE: 1
- 3. The module only has positioning function and needs to be used with a magnetic compass.
- 4. The white side needs to face up, without obstruction, and there is no installation direction requirement.
Note: A8A and A8AS share the same wiring logic and performance specifications, differing primarily in physical dimensions and weight.
