 I think I'm up to 6 R-Pi (one running Pi-Star, the other is my HTTP
server -- 2@3B, 2@3B+, 4B 2gb, 4B 4gb), only 2 BBB, an BB AI (not
recommended for experimenting unless one is comfortable with
editing/building device tree files -- the BBB has run-time pin-muxing, not
the BB AI).

 But I've also got 6 TIVA-C boards, 4 or 5 Arduino, 2 Metro, some
ancient BASIC Stamps, and a few Propeller boards.

 If you need lots of hardware timers -- the TIVA TM4C123 must be a
winner. Six 64-bit and six 32-bit timers -- and each of those can be split
into two half-width timers. ARM M4F core, 12-bit ADC. No OS overhead 

 In contrast, the Propeller has 8 simple cores, running in lockstep, and
NO INTERRUPTS (the idea was that one would dedicate a core just to polling
whatever would create an interrupt).
