[Introduction]：EWD108-GN03 (TTL) multi-mode GNSS positioning module is a positioning terminal that supports multiple positioning systems (BDS/GPS/GLONASS positioning system). The device outputs positioning information through the Modbus RTU protocol, supports the output of RMC-ASCII strings that comply with the NMEA0183 protocol and separate registers for storage (longitude, longitude direction, latitude, latitude direction, etc.), and the serial port baud rate can reach up to 115200bps, which can be easily modified through the Modbus RTU protocol, which is convenient and fast.
