Figure 1: The Diminutive MCU on a 3 inch breadboard, color inverted
In my last blog post on this topic from over a year ago, I walked through the setup of a development environment for the Photon MCU board (a board made by Particle, a company which is not associated with this author or site in any way. I really like their MCU boards though!). Recently, I decided that the AMD-64, with its tether (in the form of a 110V power plug), its twenty pounds, and its voracious appetite for power, was a poor development machine for a 4 gram MCU board. OK – that was a (slight) under-exaggeration.
