Breakout Board

BYOB - Bring Your Own microcontroller Board

The Macchina M2 was designed to be modular to give you the option of using your own microcontroller board in place of our Arduino-based processor board. We've built a breakout board to make it easy to connect a Raspberry PI, Edison, Particle, or whatever your favorite microcontroller may be.

We've broken out all of the necessary signals to make it easy to hook up. Below is a rendering of the top of the breakout board showing where each signal is found. See the tables below for further description of how pins work.

At a bare minimum, connect +5VOUT and GND to your microcontroller board, supply the interface board with +3.3V at +3.3VIN, and connect up whatever signals you are looking to interface with (CAN, LIN, etc)
