Ecumaster Steering Wheel CAN Bus Board V3

Ecumaster Steering Wheel CAN Bus Board V3

The Ecumaster Steering Wheel CAN Bus Board V3 is a compact CAN switch board designed to transfer switch states, rotary switch positions, and analogue signals over CAN bus.

Measuring only 25 × 25mm, this small but powerful board is ideal for building custom steering wheel panels, button panels, rotary switch controls, and motorsport control layouts. It allows up to 8 switch inputs and 8 analogue / rotary switch inputs to be transmitted over CAN bus, helping reduce wiring complexity and simplify communication with compatible ECUs, PMUs, dashboards, and other CAN-based devices.

The board also features 4 built-in low-side outputs, which can be activated by CAN bus messages for indicators, warning lights, or other low-current functions.

Key Features

Compact CAN Switch Board
A tiny 25 × 25mm board designed for custom steering wheel and control panel installations.

8 Switch Inputs
Supports up to 8 switch inputs, switched to ground.

8 Analogue / Rotary Switch Inputs
Includes 8 analogue inputs for 0–5V sensors, potentiometers, or rotary switch inputs, with 10-bit resolution.

4 Low-Side Outputs
Built-in low-side outputs rated at 0.5A, suitable for resistive and inductive loads.

CAN Bus Communication
Transfers switch states and analogue signals over CAN bus, reducing the amount of wiring needed between steering wheel controls and the vehicle electronics system.

Designed for EMU Black & PMU
Designed to work with Ecumaster EMU Black and PMU systems, while also being suitable for other devices with configurable CAN bus inputs.

User-Selectable CAN Speed
Supports 500kbps or 1000kbps CAN bus speeds.

Configurable CAN ID & Frame Structure
Different CAN IDs and CAN frame structures can be selected to suit the installation.

5V Sensor Supply
Provides a +5V output for powering rotary switches, sensors, and potentiometers.

Firmware Upgrade via CAN
Firmware can be upgraded over the CAN bus.
