Well, yes and no. Unless it is a hobby project you will also need sensors
and actuators, wireless network, industrial bus and other stuff which is
not small. The motherboard is not always the major contributor to the size
and weight.

If you are ready to pay higher price, there are smaller boards. E.g.

Since there is no Ada for ARM I had no opportunity to evaluate such boards
for our embedded solutions. E.g. how to access GPIO and CAN. How good (bad,
of course) GPIO is etc.

For instance ALIX boards have an AMD companion chip with GPIO. But the
contacts of AI/AO are not soldered!

P.S. If people wrote about ARM to AdaCore sales as frequently they do in
c.l.a. we would have GNAT for ARM.
