Genuine Dell OEM Junction Board

This is a genuine Dell OEM junction circuit board for the Latitude 7400 2-in-1 and Latitude 9410 2-in-1 laptops. It mounts beneath the touchpad palmrest assembly. The board connects optional fingerprint reader, RFID, and Smart Card modules to the main motherboard. Part number RKRW3 ensures correct identification.

Verify Laptop Model Before Ordering

Confirm the laptop is a Latitude 7400 2-in-1 or Latitude 9410 2-in-1 before purchase. This board is not compatible with standard clamshell versions or other Dell families. Check the existing board for the RKRW3, EDB41, or LS-G441P markings to ensure an exact match. The part is new and matches the product images supplied.

Integrates With Palmrest Assembly

The circuit board sits on the underside of the touchpad palmrest and routes signals from peripheral modules to the system board. It frees the main motherboard from direct connector density for those accessories. Installation requires palmrest removal and careful flex-cable routing. No separate drivers are needed; the board is a passive interconnect.

Questions about this item

What comes in the box and do I need to buy the palmrest separately?

The listing supplies the RKRW3 junction circuit board only; the palmrest assembly, fingerprint reader, RFID module and Smart Card reader are not included and must be sourced separately.

How do I choose between the RKRW3, EDB41 and LS-G441P part numbers?

All three numbers refer to the same Dell OEM junction board for the Latitude 7400 2-in-1 and 9410 2-in-1; order by any one of them and you will receive the identical component.

What does the RKRW3 board do once it is installed in a Latitude 7400 2-in-1?

It sits under the touchpad palmrest and routes signals from optional fingerprint, RFID and Smart Card modules to the main motherboard so those features function.
