Datasheet (mosaic-G5 P3)Product Overview
Achieve survey-grade, millimeter-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.
- Millimeter-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-synchronization 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.
- RTK Base functionality due Q2 2026: The initial mosaic-G5 P3 firmware does not support RTK Base and it can not generate RTCM corrections. Septentrio will add base station capability to the mosaic-G5 P3 and P3H in a firmware release currently planned for the Q2 2026.
This Breakout requires an external multi-band antenna. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.
