Gravity GNSS BeiDou GPS Receiver Module I2C and UART

The Gravity GNSS module (TEL0157) from DFRobot receives GPS, BeiDou and GLONASS, individually or combined. With several systems more satellites are available, and the position is determined more accurately and faster, even between buildings. The module is based on the Quectel L76K and delivers longitude, latitude, altitude, time, speed and course via I2C or UART; a switch on the board selects the interface. An active ceramic antenna is included.

Note: The module only uses the satellite signals, without assistance via WiFi or mobile network like a smartphone. Therefore operate it outdoors, on the roof or at a window. The LED lights red without reception and green as soon as signals are received.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
