Matek GPS & Compass Module M8Q-5883

This is a tiny GPS module with an integrated compass sensor form Matek.  Designed to be used when your aircraft does not have much space, the Ublox M8Q module insures you get accurate position information.   This unit is designed to work with Inav, Betaflight and also ardupilot (3.5.4+) systems.  The integrated compass module is essential for multirotor applications and allows you to mount the GPS/compass module away from sources of interference to give you the best possible position accuracy.

Features

• 72-channel u-blox M8 engine GPS L1C/A, SBAS L1C/A, QZSS L1C/A, QZSS L1 SAIF, GLONASS L1OF, Galileo E1B/C
• On-board Ultra low noise 3.3V voltage regulator and RF filter for noise blocking
