Out of Stock

The Pixhawk I2C Port Expand Board is a passive splitter that adds four additional I2C bus connections to Pixhawk and APM-series flight controllers, enabling the integration of multiple peripherals like compass modules, digital airspeed sensors, and LED strips.

Features

  • Expands a single I2C port to four independent connections for peripheral devices.
  • Includes a 4-wire (VCC, GND, SDA, SCL) cable for direct connection to the flight controller.
  • Housed in a compact, lightweight plastic casing for protection and easy mounting.
  • Plug-and-play compatibility with Pixhawk, Pixhawk 2, and APM flight control systems.
  • Enables simultaneous use of multiple I2C sensors like compasses, airspeed sensors, and RGB LEDs.

Description

This I2C port expander addresses a common limitation in Pixhawk and APM autopilot systems, which typically feature only one dedicated I2C interface. The board passively splits the I2C bus signals, allowing pilots and builders to connect up to four additional I2C-compatible devices without requiring complex wiring or external power.

The unit is supplied with a pre-wired cable and housed in a durable plastic shell, providing a robust and organized solution for expanding sensor capabilities in autonomous UAVs, rovers, and other robotic platforms running ArduPilot or PX4 firmware.

Key Features

  • Four-port I2C bus splitter for Pixhawk/APM flight controllers.
  • Includes a ready-to-use 4-wire connection cable (VCC, GND, SDA, SCL).
  • Compact plastic enclosure protects the PCB and simplifies installation.
  • Passive design requires no external power or configuration.
  • Facilitates complex builds requiring multiple I2C sensors (e.g., dual compasses for redundancy).
  • Lightweight construction minimizes impact on overall vehicle weight.

Applications

  • Expanding sensor suites on Pixhawk-based autonomous drones and rovers.
  • Adding redundant compass modules for improved navigation reliability in ArduPilot/PX4 vehicles.
  • Integrating multiple I2C peripherals like digital airspeed sensors, LED strips, or additional telemetry devices.
  • Educational and prototyping platforms requiring multiple I2C connections.

Frequently Asked Questions

What flight controllers is this I2C expander compatible with?

This expander is directly compatible with Pixhawk, Pixhawk 2, and APM-series flight controllers running ArduPilot or PX4 firmware. It connects via the standard 4-pin I2C port using the included cable. Ensure your firmware supports multiple I2C devices on the same bus.

Does this board require external power or configuration?

No, it is a passive splitter. It draws power (5V VCC) and signals directly from the flight controller's I2C port via the cable. No software configuration or drivers are needed; it simply provides additional physical connection points for I2C peripherals.

What is the maximum number of devices I can connect?

The board provides four separate ports. The total number of devices is ultimately limited by the I2C bus protocol and address conflicts. You can connect up to four devices directly, but you must ensure each has a unique I2C address. Some sensors allow address changes via solder bridges.
