FIRST Robotics Competition Documents
This document is designed to help you create myRIO Expansion Port (MXP) boards for roboRIO.
We will continue to update this document before and during the FRC season, so be sure to check back as you work on your design. If there is any information that you are missing please leave a comment below. If your team creates an MXP board, please share it with FIRST@ni.com so we can share your board with other teams.
Be sure to check out the MXP guidelines from FIRST to know which boards will be legal for FRC competition.
MXP Board Mechanical Drawings
These mechanical drawings include all of the critical dimensions and hole placements for creating an MXP board.
MXP Pinouts
Use the following pins to connect your MXP board to the roboRIO. Note that many of the lines can serve multiple functionality.
Connectors
These are critical components you may need to build your own MXP adaptor boards. These parts are avalible through many distributors including DigiKey & Jameco. Some parts may have a long lead time, so be sure to order them ASAP so you have time to get everything before you need to finalize your robot designs.

Multisim & Ultiboard
Multisim is an industry-standard, best-in-class SPICE simulation environment. It is the cornerstone of the NI circuits teaching solution to build expertise through practical application in designing, prototyping, and testing electrical circuits.
More Info -> What is Multisim?
The Ultiboard interface enables efficient layout and routing of PCB designs. Integration with NI Multisim allows seamless transfer of schematics to layout.
