Written by Kipp Bradford Illustrated by Rob Nance YOUR BOARD 1 Computing Boards can be divided into two categories: those that can run Linux, like Raspberry FROM 2 Indicating Pi, and those that can’t, like an Arduino Uno. While this is a completely arbitrary 3 Resetting ARDUINO TO distinction, it is also a useful one because it helps to describe what you should expect 4 Powering in terms of board features, complexity, power consumption, and programmability. For PI, HERE’S A 5 Interacting the sake of description, we’ll call boards that can run Linux “advanced” and those that BREAKDOWN 6 Communicating can’t “basic.” Here’s a breakdown of what matters about any given board.
