Overview
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.

Features
Multi-constellation receiver support, concurrent reception of up to 3 types of GNSS satellite systems from GPS, Beidou, Galileo, and GLONASS, and still retains low power consumption
Augment systems support, including SBAS, QZSS, IMES, D-GPS, improving the positioning performance of service location
A-GNSS (Assisted GNSS) support, reducing the first positioning time when powered up, improving the acquisition sensitivity
Features -167dBm navigating sensitivity and outstanding ability for anti-spoofing & anti-jamming, supports geo-fencing
Supports U-Center, an easy way to config the module
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Onboard USB TO UART converter CP2102 for serial debugging
Breakouts the module's UART and I2C interface, for connecting with host boards like Arduino/STM32
Baudrate range: 4800~921600bps (9600bps by default)
Supports DDC (I2C compliant) interface: up to 400KHz (max)
Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
4x LEDs for indicating the module operating status
