Wave Pi HAT GPS MAX-8Q

This is a Raspberry Pi GNSS HAT based on MAX-M8Q with multi-constellation receiver support, which means up to 3 types of GNSS satellite systems can be used together, including GPS, Beidou, Galileo, and GLONASS. It also support augment systems like SBAS, QZSS, IMES, and D-GPS. It features accurate & fast positioning with minor drifting, low power consumption, outstanding ability for anti-spoofing & anti-jamming, and so on.

By simply attaching it onto the Pi, it is fairly easy to enable GNSS capability for your Raspberry Pi.
