CAN Bus Keypad

Description

Overview

Built for performance and flexibility, the LD Performance CAN Bus Keypad puts six fully programmable RGB buttons in one tough, easy-to-use unit.

Each button can be mapped to control your ECU, PDM, or CAN-based accessory, letting you manage boost, traction, antilag, lighting, or any custom input instantly.

Key Features

• 6 RGB backlit buttons — customizable colors and button inserts
• Adjustable CAN bus speeds and IDs for perfect ECU integration
• USB Type-B port for easy firmware updates
• Compatible with BlinkMarine CANopen and Ecumaster J1939
• Works with multiple CAN devices simultaneously

Compatibility

The LD Performance CAN Keypad works with a wide range of systems, including:

• LD Performance PDM

Pinout

The keypad requires power and a CAN connection.

To ensure signal stability:

• Twist CANH and CANL wires together.
• When connecting more than two devices on the same network, use a ring topology (not star).
• Place 120Ω termination resistors at each end of the CAN bus.
