This document describes the hardware features and specifications of the SAM-M8Q patch antenna module, which features the u-blox M8 concurrent GNSS engine with reception of GPS, GLONASS, Galileo and QZSS signals.
This manual provides detailed instructions for integrating the u-blox SAM-M8Q patch antenna module into designs. It covers hardware features, power connections, UART and DDC interfaces, I/O pin functions, and PCB layout recommendations. The module supports concurrent GNSS signals and is designed for automated SMT assembly. It includes guidelines for handling, soldering, and EMI precautions to ensure reliable operation.
The document references external resources such as the SAM-M8Q Data Sheet and Receiver Description for protocol and specification details. It also includes sections on product handling, design considerations, and troubleshooting support contacts for technical issues.
| GNSS Signals Supported | GPS, GLONASS, Galileo and QZSS |
|---|---|
| Package Type | LGA |
| Power Supply Pins | VCC, VCC_IO, V_BCKP |
| UART Interface | RxD/TxD, configurable baud rates |
| DDC Interface | I2C-compatible, slave mode only |
The SAM-M8Q supports GPS, GLONASS, Galileo and QZSS signals.
The module requires three power supply pins: VCC (main supply), VCC_IO (IO supply), and V_BCKP (backup supply for RTC and BBR).
The V_BCKP pin supplies the real-time clock (RTC) and battery-backed RAM (BBR) in case of power failure, enabling hot or warm starts.
