Pixhawk I2C Port Expand Board with Cable
The Pixhawk I2C Port Expand Board is a passive splitter module that adds four additional I2C bus connections to Pixhawk and APM flight controllers, enabling the simultaneous use of multiple I2C peripherals like external compasses, digital airspeed sensors, and RGB LED modules via a single 4-wire cable.
Features
- Expands a single I2C port to support up to four additional I2C peripheral devices.
- Includes a 60mm 4-pin cable for direct connection to Pixhawk/APM flight controllers.
- Compact PCB design measuring 34mm x 12mm with a net weight of only 3 grams.
- Features five parallel vertical 1.25mm 4-pin sockets for convenient daisy-chaining.
- Enables simultaneous connection of peripherals like external compasses, airspeed sensors, and LED modules.

Designed for Pixhawk and APM-based autopilot systems, this I2C port expander addresses the limitation of a single I2C interface by providing a parallel bus splitter. The board routes the SDA, SCL, VCC, and GND lines to four additional ports, allowing multiple I2C devices to share the same bus with unique addresses. Its passive design requires no configuration or firmware, making it a plug-and-play solution for expanding sensor capabilities.
The compact 34mm x 12mm PCB is built with durable FR-4 material and features 1.25mm pitch JST-GH style connectors, ensuring a reliable and lightweight integration into multirotor, fixed-wing, and rover builds. The included 4-wire cable provides a direct link to the flight controller’s I2C port, simplifying wiring and reducing clutter in complex autonomous vehicle setups.
