OSHUG 39 — Piano Forte, Ken Boak

** Recording from a joint OSHUG & BCS Open Source Specialist Group meeting, London, 19th March 2015.

Many modern electronic products are built from a series of building blocks - generally consisting of a microcontroller, a power supply and a communications interface - these days, usually wireless.

If you put these three subsystems together onto a pcb you will then have the basis for creating some interesting devices.

Unfortunately, most dev boards don't tend to give you all these elements, sometimes you just get the microcontroller and power supply, but little or no thought has been given to the communications interface - which is of course how you get the data in and out.
