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.

● 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
