Holybro M10 Secondary GPS with 6 Pin connector
by Holybro

The Holybro M10 Secondary GPS is a premium navigation and heading tracking module driven by the advanced u-blox M10 series concurrent GNSS receiver. Engineered for redundant array setups, Beyond Visual Line of Sight (BVLOS) mission profiles, and commercial industrial drone configurations, this "Secondary GPS" or "GPS2" variant features a specialized 6-pin JST-GH connector interface. It is purposefully wired for plug-and-play integration into the secondary GPS port or the combined 6-pin UART/I2C peripheral arrays found on Pixhawk standard architectures, Cube flight controllers, and specialized enterprise avionics ecosystems.

By leveraging 10th-generation u-blox multi-constellation firmware, the module tracks up to four distinct GNSS networks simultaneously—including GPS, GLONASS, Galileo, and BeiDou. This multi-band approach dramatically increases tracking reliability, delivers superb signal retention near tall structures, and reduces Time-to-First-Fix (TTFF) metrics. Housed in a compact, durable 50mm aerodynamic shell, it bundles a high-gain 25 x 25 x 4 mm ceramic patch antenna with an integrated LNA MAX2659ELT+ RF amplifier, an internal IST8310 digital magnetometer for compass headings, a hardware safety switch, an internal audible buzzer for system telemetry alerts, and a bright tri-colored RGB UI status indicator LED.
