“I make things, mostly technological, but don’t hold me to that, consistency is not a human virtue. Electronics and software, cast iron and plastics, microcontrollers in vintage automobiles, faux historical machinery that could (not) have been; finely crafted, rigorously rugged, reliable, most often.”
The Model 01a (aka M01a) is a 3″ x 5.5″ self-contained controller board designed for embedded applications. It’s based around Microchip Inc’s in-circuit-programmable 14-bit PICs, and contains I/O expansion, a power supply and various goodies that I found useful in five years of using my previous controller board design.
The M01 board contains enough support hardware to pull off a lot of functionality. Before I get to handling common interface problems here’s a function-by-function description of the hardware. There’s some subtlety to some of the design that’s worth paying attention to.
