Vex and Arduino

For a project I am working on, I am connecting vex motors to an Arduino and using a Myo to gesture control a vex robot. I need to make schematics for the manual as I am finishing up the project, has anyone happened to create or know where I can find an already created motor controller 29 that I can insert into a circuit schematic program such as or fritzing?

I doubt you’ll find a schematic at all, let alone one ready-made for a certain program.

This is the most detailed discussion I could find
