Overview
The Beitian M9/M10 GNSS receiver module (Model options: BE-565 / BK-565) is a compact GNSS receiver module designed for UAV flight control and other positioning systems. It supports multiple satellite constellations and outputs positioning/time data via TTL UART using NMEA-0183 and UBX protocols, with a built-in QMC5883L electronic compass and an RGB status LED.

Details

Multi-constellation GNSS + compass in a compact puck-style module for UAV flight controllers, with TTL UART output.

Standard NMEA sentences make it easy to read position, speed, time, and satellite details over TTL UART.

Simple TX/RX wiring supports quick bench testing with a USB‑to‑TTL adapter or direct connection to a controller UART.

Lightweight, low-profile housing with a 61.3 mm diameter footprint helps keep installations tidy on tight builds.

Suitable for positioning and navigation projects across drones, unmanned vehicles, and robotics.


A 6‑pin connector provides power, UART TX/RX, and I2C lines for the built‑in QMC5883L compass.
