Holybro M10 IST8308 Secondary GPS with 6 Pin connector
by Holybro

The Holybro M10 GPS with Secondary 6-Pin Connector (IST8308) is a high-precision, multi-constellation GNSS navigation module engineered for redundant dual-GPS configurations, Pixhawk GPS2 expansion, and Cube flight controller setups. Powered by the 10th-generation u-blox M10 GNSS engine, this module concurrently receives signals from up to four major satellite constellations (GPS, GLONASS, Galileo, and BeiDou), delivering rapid satellite acquisition and high positioning accuracy in complex flight environments.

Pre-terminated with a 6-pin JST-GH connector, this secondary variant plugs directly into 6-pin UART & I²C or GPS2 ports on Pixhawk standard baseboards and Cube autopilots. Equipped with an updated IST8308 digital compass, a high-gain 25x25x4mm ceramic patch antenna, MAX2659ELT+ LNA RF amplifier, onboard safety switch, audible buzzer, and a tri-color RGB status LED, it provides complete flight feedback and heading reference for mission-critical drone builds.

Key Features

• u-blox 10th Gen M10 GNSS Core: Concurrently tracks up to 4 major satellite systems (GPS, GLONASS, Galileo, BeiDou) for fast cold starts and reliable position lock.

• Secondary 6-Pin JST-GH Interface: Specifically wired with a 6-pin JST-GH cable for direct connection to GPS2 / UART & I²C ports on Pixhawk standard carrier boards and Cube flight controllers.

• Updated IST8308 Magnetometer: Integrated digital compass provides accurate heading orientation, supported in modern PX4 (v1.14.3+) and ArduPilot (4.4+) firmwares.

• Integrated Avionics Suite: Features an onboard safety switch, audible buzzer, and ultra-bright tri-color RGB LED indicator for direct ground-handling interaction and status feedback.

• High-Gain Active Antenna Array: 25x25x4mm ceramic patch antenna paired with a low-noise 3.3V regulator and LNA RF amplifier for maximum signal reception.

• Farah Supercapacitor Backup: Integrated rechargeable capacitance retains satellite ephemeris data for rapid warm and hot start locks.
