MAX-7Q GNSS HAT
GNSS Module Based On MAX-7Q For Raspberry Pi
Accurate & Fast Positioning With Minor Drifting, Low Power Consumption, Outstanding Ability For Anti-Spoofing & Anti-Jamming
This is a Raspberry Pi GNSS HAT based on MAX-7Q, which supports positioning systems including GPS, GLONASS, QZSS, and SBAS. 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.
Features At A Glance
- Supports GPS/QZSS, GLONASS positioning systems
- A-GNSS (Assisted GNSS) support, reducing the first positioning time when powered up, improving the acquisition sensitivity
- 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)
