UBlox MAX-M8W based Multi GNSS module

UBLOX MAX-M8W GPS/QZSS GLONASS BeiDou 18Hz receiver Reference Board with SMA antenna connector for your mini UAV systems, Robots, RC, FPV,Arduino, Raspberry or other projects. Ultra small and light.

The MAX-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the u-blox M8 engine in the industry proven MAX form factor. With dual-frequency RF front-end, the u-blox M8 concurrent GNSS engine is able to intelligently use the highest amount of visible satellites from two GNSS (GPS, GLONASS and BeiDou) systems for more reliable positioning. The MAX-M8 series is ideal for performance driven applications. The MAX-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power. The MAX-M8Q provides best performance for passive and active antennas designs. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments. The MAX-M8 combines a high level of integration capability with flexible connectivity options in a miniature package. This makes MAX-M8 perfectly suited for industrial applications with strict size and cost requirements. The MAX-M8Q is also halogen free (green) which makes it also a perfect solution for consumer applications. The DDC (I2C compliant) interface provides connectivity and enables synergies with most ublox cellular modules

Size: 25x35mm


Connecting TTL serial module

After connecting the device and want to use the Galileo network need to set the NMEA protocol version first:

Ucenter nmea.png

When the NMEA is set, need to enable the wanted GNSS constellations at the GNSS page:

To save the configuration into the module select the CFG page, and save into the BBR (battery backuped ram)
