SparkFun Allband GNSS RTK Breakout - mosaic-G5 P3

Achieve survey-grade, millimetre-level precision in your most power-sensitive projects with the SparkFun mosaic-G5 P3 Allband GNSS RTK Breakout. With Septentrio's mosaic-G5, you'll receive a compact GNSS peripheral that delivers the same leading performance as the mosaic-X5 but in a package that is 60% smaller and consumes 40% less power. This breakout is the preeminent choice for surveying, robotics, and other IoT applications where size, weight, and power (SWaP) are critical constraints.

This is a dedicated, standalone breakout board designed to get you up and running immediately, featuring standard 0.1" headers, Qwiic connectors, and a sturdy SMA antenna connection.

Compact Size, Best-in-Class Precision

Don't let the footprint fool you. The mosaic-G5 is a multi-band, multi-constellation receiver capable of tracking all major global systems (GPS, GLONASS, Galileo, BeiDou, QZSS) simultaneously.

• Millimetre-Level Accuracy: Delivers 6mm horizontal and 1cm vertical accuracy with RTK.
• Precise Timing: Features a PPS timing resolution of 1.4ns and event-trigger accuracy <3ns, making it ideal for exact time-synchronisation applications.
• AIM+ Interference Mitigation: Equipped with Septentrio's AIM+ technology, which offers some of the best protection against jamming and spoofing on the market, ensures reliability in hostile RF environments.

Designed for Integration & Connectivity

We've designed this breakout to be as versatile as the module itself, giving you access to all the critical interfaces you need.

• Extensive Breakout: Twenty-one 0.1"-pitch PTH pins break out two UARTs, two configurable PPS outputs, two event triggers, and GPIOs.
• USB-C Connectivity: A native USB-C connector supports high-speed data transfer and configuration.
• Ready for RTK Corrections: The UART2 interface is broken out to a locking JST connector and a BlueSMiRF-compatible header, making it easy to connect an RF transceiver to receive RTCM corrections.
• Qwiic Compatible: Includes two Qwiic connectors for easy, solder-free integration into the SparkFun Qwiic Ecosystem.

Configuration & Advanced Control

The mosaic-G5 offers professional-grade control for advanced users.

• Flexible Protocols: Supports industry-standard NMEA, RTCM v3.x, and the highly efficient Septentrio Binary Format (SBF).
• Sophisticated Software: Configure and monitor the module using Septentrio's RxTools suite or via a robust Command-Line Interface (CLI) over USB or Serial.

This Breakout requires an external multi-band antenna. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.
