Ecumaster Steering Wheel CAN BUS Board V3 The Ecumaster Steering Wheel CAN BUS Board V3 is the professional solution for integrating steering wheel controls into your vehicle's CAN BUS network. This ultra-compact module is designed to fit inside the cavity of most aftermarket steering wheels (such as OMP, Sparco, or Momo), allowing you to convert up to 8 push-buttons and 2 rotary switches into a single, high-speed digital data stream. By utilizing the V3 board, you eliminate the need for a complex "curly cord" loom with dozens of wires. Instead, a simple 4-wire connection (Power, Ground, CAN H, CAN L) provides full control over your Ecumaster ADU, PMU, or EMU Black. The V3 iteration features improved hardware for enhanced signal stability and a wider voltage input range, making it the industry standard for professional GT, rally, and drift cockpits. Technical Authority & Key Features 10 Total Inputs: Supports 8 digital switch inputs (pull-to-ground) and 2 dedicated analog inputs designed specifically for 8-position rotary switches. Streamlined Wiring: Replaces bulky multi-core cables with a lightweight 4-wire CAN interface, reducing steering column clutter and weight. Direct ADU/PMU Integration: Easily map buttons for page swapping, lap timing resets, pit speed limiters, or traction control levels via the Ecumaster Light Client. On-Board 5V Output: Provides a regulated 5V supply to power external sensors or rotary switches directly from the board. Compact Footprint: Measuring just 25mm x 25mm, the square PCB is designed to be tucked behind the horn button or within a custom steering wheel plate. User-Configurable CAN IDs: Fully programmable CAN bitrates (up to 1Mbps) and message IDs, ensuring compatibility with almost any aftermarket logger or ECU. Backlit Support: Includes a dedicated output for illuminating buttons or LED indicators on the steering wheel plate.
