iRobot® Create® 3 Hookup Guide for NavQPlus by NXP®


This is community-submitted content. Please feel welcome to submit PRs for additions or corrections.

The iRobot® Create® 3 robot has a USB-C®1 connector implementing a USB 2.0 host capable of 5 V @ 3 A continuous, which can be used to power and communicate with various downstream devices.

NavQPlus is an open source reference design provided by NXP® and manufacturable by anyone. Since NavQPlus has USB-C® ports capable of being configured as a USB Ethernet Gadget, a cable with a USB-C® connector on both ends is all that is required.


  • Unless set otherwise, the default USB-C® port for use as an Ethernet Gadget device is configured to only the centermost USB-C® port (labeled USB 2) as shown in the example pictures.

The NavQPlus is pictured in the cargo bay using the 3D-printed adapter plate and on top of the faceplate using the 3D-printed case. Hookup diagram for NavQPlus with adapter mount in cargo bay Hookup diagram for NavQPlus with case on faceplate

Printable Case

The NavQPlus has a printable case specifically designed for use with the Create® 3, allowing for it to be mounted to the faceplate or cargo bay. The base of the case attaches to the NavQPlus using the existing four (4) M2.5-0.45 x 12mm System On Module (SOM) mounting screws.


  • The top case is designed to be fastened together to the base of the case with four (4) M3-0.5 x 10mm screws if not mounted to a Create® 3 plate or M3-0.5 x 12mm if mounted; cap head is suggested.
  • For best results, it is suggested to tap/thread the M3-0.5 on the top case and M2.5-0.45 (SOM) holes on the base case.

Printable Adapter

If a more minimal mount is desired instead of a case, an adapter plate using the existing SOM mounting screws for fastening is also provided.


  • This adapter is designed to be fastened to the Create® 3 plate with four (4) M3-0.5 x 6mm screws; cap head is suggested.
  • For best results, it is suggested to tap/thread the M3-0.5 (Create® 3 mounting) and M2.5-0.45 (SOM) holes.
