MicoAir MG-902 is a GPS module with a U-Blox M9 chip and a QMC5883L compass, offered at an affordable price. The M9 chip supports all L1 GNSS signals (GPS, GLONASS, Galileo, BeiDou) and can lock onto up to 32 satellites. Its biggest advantage is the high refresh rate of up to 25Hz. The GPS module features a 25x25x4mm patch antenna for strong signal reception.
The status of the GPS module is indicated by an LED. The blue LED is constantly lit when powered on and blinks once a 3D fix is acquired.
