Description Boardoza UBLOX SAM M8Q GNSS Module is a compact multi-GNSS receiver breakout board for positioning, navigation, tracking, drone, robotics, and IoT geolocation projects. Built around the u-blox SAM-M8Q receiver, it supports multiple satellite constellations for more reliable location data in embedded applications. The module operates from 3.3V to 5.5V and provides both I2C and UART communication interfaces. Additional PPS, RST, INT, and SAFE pins are available for timing, reset, aiding, and configuration-related functions, while the 40mm x 40mm board format makes the module straightforward to integrate into prototypes and custom devices. Features Multi-GNSS receiver: supports GPS, GLONASS, Galileo, and BeiDou satellite systems. u-blox SAM-M8Q module: designed for precise positioning and reliable GNSS performance. Flexible power input: operates from 3.3V to 5.5V for compatibility with common MCU platforms. I2C and UART interfaces: choose the communication interface that best fits the project. PPS timing output: provides a default 1 pulse-per-second time pulse for synchronization applications. Additional function pins: includes RST, INT, and SAFE pins for reset, aiding, and SAFEBOOT_N use. Wide operating temperature: official documentation lists -40°C to +85°C operation.
