BeagleBone-Black

[Louis Mamakos]

It does, however, have a couple of embedded RISC microcontrollers ("PRU" - Programmable Real-Time Unit) which can be used to do various tricks with the I/O pins that might be interesting for some applications.  Sort of what the PIC devices could do; complex programmable bit-banging and I/O vs. having dedicated or special purpose hardware peripherals.  These microcontrollers have some sort of mailbox communication means with the ARM core so that they can each get the other's attention.

For example, make a few more extra "soft" UARTs:  http://processors.wiki.ti.com/index.php/Soft-UART_Implementation_on_AM335X_PRU_-_Software_Users_Guide

The Beaglebone Black looks really neat; more I/O pins than the RPi.  I might have to get one, hopefully it won't end up on the pile of all the other cool widgets.
