Well, you shouldn't run out of pins with the 2560. I've got a few Uno R3s
laying around and a couple of Nano 33 BLE Senses. The Nano is used in a
MIT ML course and they picked it because of all the onboard sensors rather
than a bunch of loose components. It's based on the Nordic Cortex M4 uc.

   pretty damned good too, have used that with solar-powered units

There were quite a few. I used to subscribe to Steve Ciarcia's 'Circuit
Cellar' and PIC projects were very popular.

   But is Cortex-based REALLY a "PIC" ???
 
   16F84 was a PIC.

   So small, so cheap, so versatile. I've even used them to emulate
   ordinary logic gates if speed was not super-critical ... that cheap,
   and can be most anything you want, even drive a serial display.

I've got some chips with a bunch of little legs that I assume are legacy
AVRs. You could do a lot with them,

   However the bigger pain/expense lies in the 'development
   systems/boards'. You don't just buy the chip - you have to be able to
   program it too. Discourages experimenters.

Yeah, the $215 is a barrier and then you wind up with a dead bug you have
to do something with. Of course you can go a lot cheaper:

Walmart? Yeah I'm sure the local superstore has a bunch of them. Must be
something similar for PICs or you can roll your own.
