Details

The BE-289 pairs a compact M10050 receiver with serial output and a separate SMA-K antenna connection.

Model comparison highlights the BE-289's place in the Beitian GNSS module range and its compact board layout.

Satellite signals feed the module, then positioning data is sent back to the host device through the serial port.

Signal charts support the positioning claims with visible satellite tracking and data reception feedback.

The module can output standard NMEA data fields for time, position, satellite status, and ground speed.

Wiring details and use cases make integration easier for drones, vehicle navigation, and other embedded projects.
