Beitian Dual BN-220 GPS GLONASS Antenna Module TTL Level RC Drone. This BN-220 GPS Module can show your speed. When you use it for Raspberry Pi, there is no driver needed. The data output when the TX LED flashing in blue; PPS LED not bright when GPS not fixed, flashing in red when fixed

Module Pin
1. GND, grounded
2. TX, data module output
3. RX, data entry module
4. VCC, power supply module, 2.8V-6.0V

Package Includes:

1 x Beitian Dual BN-220 GPS GLONASS Antenna Module TTL Level RC Drone
