The DD-EFI Breakout Board is designed to simplify the wiring process when connecting sensor inputs to your digital dash or ECU. It neatly breaks out the essential connections—5V reference, sensor signal, and sensor ground—for each input, making sensor integration cleaner and more efficient.

Key Features

• Simplified Sensor Wiring
  Cleanly breaks out each sensor’s 5V vRef, signal, and ground—no splicing or custom harnessing required.

• Integrated Pull-Up Resistors
  Supports both LDM Combo and OEM temperature sensors with onboard pull-up resistors:

  • 240 ohm for LDM Combo Sensor

  • 2.49k ohm for OEM Temperature Sensor

• Configurable via DIP Switches
  Easily select the appropriate pull-up configuration for each input using built-in DIP switches—no soldering required.

Ideal For

• Users installing DD-EFI digital dashboards

• Megasquirt ECU users needing clean sensor integration

• Simplifying installation of temperature and pressure sensors
