Try doing that with a x86 based board. They are also cheap, very small in size, and have various I/O options including (usually) plenty of GPIO pins. Take a look here: https://www.olimex.com/Products/ Olimex are very popular with hobbyists here in Europe and they produce a large range of boards including, but not restricted to, ARM. > Anyway, the thingy should run Linux.

For a number of projects, running Linux would be serious overkill and, on a technical level, would not be suitable if you have hard real time requirements (although there are various RT extensions which might be suitable in some circumstances). GNAT is running on ARM under RTEMS. I don't know what the current bare metal status is for ARM, although people have posted in the past in c.l.a about work they have done on this.
