## Description

The SparkFun Triband GNSS RTK Breakout features Septentrio's mosaic-X5, an ultra-low power multi-band, multi-constellation GNSS receiver capable of delivering centimeter-level precision. Supporting L1, L2, and L5 bands simultaneously, this breakout provides access to GPS, GLONASS, Beidou, Galileo, NavIC, SBAS, and QZSS constellations. With Real Time Kinematics (RTK) capability, the mosaic-X5 can operate as a base station broadcasting correction data or as a rover achieving horizontal accuracy of 6mm and vertical accuracy of 1cm. The module features Septentrio's AIM+ technology for interference mitigation and anti-spoofing. No programming is required — the built-in web server allows full configuration and data logging through a standard browser via USB. Key Features Triband GNSS – Simultaneous L1, L2, and L5 band reception across multiple constellations RTK Precision – 6mm horizontal and 1cm vertical accuracy with RTK corrections 100Hz Update Rate – High-speed position updates for automotive and industrial applications 5ns Timing Precision – Ultra-precise timing output via PPS AIM+ Technology – Advanced interference mitigation and anti-spoofing protection No Code Required – Built-in web server for configuration, data logging, and control via USB One-Button Logging – Start/stop data logging and mount/unmount SD card with a single button USB-C Interface – Powers the board and provides access to web interface and CLI Specifications GNSS Module – Septentrio mosaic-X5 Module Voltage – 3.135V to 3.465V (500mA max) I/O Logic Level – 3.3V Connectors – USB-C, 2× SMA (antenna + PPS), 6-pin JST GH (GHR-06V-S) Storage – µSD card slot (up to 32GB, FAT32) Cold Start – < 45 seconds Warm Start – < 20 seconds Reacquisition – 1 second Latency – < 10ms Antenna Voltage – 3.0V to 5.0V (150mA max) Interfaces – 4× UART, USB 2.0, SD card, GPIO/LEDs ESD Protection – Built-in protection diodes Supported Constellations GPS – L1C/A, L1PY, L2C, L2P, L5 GLONASS – L1CA, L2CA, L2P, L3 CDMA Beidou – B1I, B1C, B2a, B2b, B2I, B3 Galileo – E1, E5a, E5b, E5 AltBoc, E6 QZSS – L1C/A, L1 C/B, L2C, L5 NavIC – L5 SBAS – EGNOS, WAAS Status LEDs Power – Red Pulse-Per-Second – Yellow Data Logging – Green PVT Solution – Blue RTK Mode – White Ideal For High-precision GNSS surveying and mapping RTK base station or rover setups Autonomous vehicle navigation Precision agriculture Timing applications requiring nanosecond precision Note: A multi-band GNSS antenna supporting L1/L2/L5 frequencies is required but not included. Pair with a suitable triband surveying antenna for optimal performance.
