TBS DroneCAN GPS Module UBX-M9140

The TBS DroneCAN GPS Module combines the ultra-fast u-blox UBX-M9140 chipset with a robust CAN bus interface. Built specifically for heavy-lift cinelifters, long-range fixed-wing platforms, and autonomous drones running ArduPilot or PX4, this module replaces traditional UART and I2C wiring with DroneCAN. This ensures rock-solid, noise-immune satellite and heading telemetry even over long wire runs, effectively eliminating the electromagnetic interference issues common in large-scale builds.

Key features

• Powered by the 9th-generation u-blox UBX-M9140 engine for exceptionally fast time-to-first-fix (TTFF) and high update rates.
• Concurrent reception of up to four GNSS constellations guarantees maximum satellite locks in challenging environments.
• DroneCAN protocol provides superior electrical noise immunity and allows simple daisy-chaining with other CAN peripherals.
• Integrated magnetometer safely isolates compass data from the electromagnetic fields generated by high-current ESCs and power lines.

Specifications

• GNSS Engine: u-blox UBX-M9140
• Interface: DroneCAN (CAN High, CAN Low, 5V, GND)
• Concurrent Constellations: 4 (GPS, Galileo, GLONASS, BeiDou)
• Supported Firmware: ArduPilot, PX4, INAV (firmware with DroneCAN support)

Because it operates entirely over the CAN bus rather than standard serial connections, this module requires a flight controller equipped with a dedicated CAN transceiver port. It is not designed for basic UART-only Betaflight stacks.
