This is a Raspberry Pi GNSS HAT based on the 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.
The board also supports augment systems like SBAS, QZSS, IMES, and D-GPS. It features accurate & fast positioning with minor drifting, low power consumption and outstanding ability for anti-spoofing & anti-jamming.
The HAT comes complete with an external antenna, USB cable, fixings and a GPIO header.
Full product Wiki and user guide available. Full specification sheet available here.
