VMX-pi Hardware Reference Manual (version 1.10)
Feature Summary
VMX-pi is designed to control a reliable, intelligent robot that is tele-operated, semi-autonomous or
fully-autonomous – when combined with an inexpensive Raspberry Pi-based processor. VMX-pi is also
usable as a Vision/Motion co-processor when paired with another robot controller.
The current recommended Raspberry Pi model is the "Raspberry Pi 3" (shown in picture on the cover
page of this document); the Raspberry Pi Zero W may also be used although it provides only a subset of
the Raspberry Pi 3 capabilities.
