MAX-M8Q GNSS HAT For Raspberry Pi, Multi-Constellation Receiver Support

MAX-M8Q GNSS HAT

GNSS Module Based On MAX-M8Q For Raspberry Pi

Accurate & Fast Positioning With Minor Drifting, Low Power Consumption, Outstanding Ability For Anti-Spoofing & Anti-Jamming

Features At A Glance

• 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
• Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
