CubePilot Cube I2C CAN BUS Splitter
by CubePilot

The CubePilot Cube I2C CAN BUS Splitter is an essential accessory for advanced UAV builds using the Cube ecosystem. This compact, passive breakout board allows you to expand a single I2C or CAN port into five separate ports, enabling the connection of multiple peripherals such as external compasses, airspeed sensors, LED indicators, or CAN-based ESCs and actuators.

Designed with the standard 4-pin JST-GH connectors used throughout the CubePilot ecosystem, this splitter ensures a secure and reliable connection for your critical avionics. It is protocol-agnostic regarding the physical layer, meaning it can be used to split an I2C bus or a CAN bus (Note: It cannot split both simultaneously on the same board; separate boards are required for each bus type). Its lightweight and small footprint make it easy to tuck into tight avionics bays, helping to keep your wiring harness clean and professional.

For sUAS manufacturers and integrators, this splitter eliminates the need for complex custom soldering or bulky Y-cables, providing a plug-and-play solution for adding redundancy and functionality to your drone.

Key Features:

• Port Expansion: Turns one I2C or CAN port into five, allowing multiple devices to share the same bus.

• Standard Connectors: Features high-quality 4-pin JST-GH connectors, the standard for the Cube/Pixhawk 2.1 interface.

• Dual Functionality: Can be used as either an I2C splitter OR a CAN bus splitter (not mixed).

• Compact Design: Small form factor (approx. 3g) allows for easy integration into any airframe without adding significant weight.

• Streamlined Wiring: Reduces cable clutter by centralizing peripheral connections.
