Overview
NANO BT RTK Receiver is based on the latest GNSS SoC and has RTK functionality. The hardware channel supports tracking all signals from all GNSS systems.
It integrates Bluetooth communication function, supporting both traditional SPP protocol and the latest BLE protocol.
Through the Bluetooth protocol, it can support input RTCM data and output NMEA data.
It can conveniently communicate with Host devices through USB Type C interface.
Additionally, It also supports UART communication using a 6P 1.25mm interface for fast communication with other devices such as Pixhawk flight controllers.
