If you're a fan of the Arduino, we have a new product you might like: the Prop-ACC (Arduino Code Compatible). Basically, we put an UNO with eight analog channels into our form factor with a good 5v power supply and eight high-current outputs (pins 2..9). All user IO is available via color-coded servo-style pin headers. It will run any of your favorite UNO libraries, because it has the ATmega328P and the standard Arduino bootloader.
I've attached a 3D image because it's easier to see, but those at Transworld can pop by our booth (#1234) and play with the real deal. It will be up on the web site and available fore sale in the next few weeks.
Here's the preliminary documentation. I have to add a section on use of the VRef header (most people won't ever need this, but it's there for those who do).
That looks like it'll be nice! Will the eight high-power outputs supply 5v or provide the same as the input voltage? Any thought of allowing a selectable output voltage of 5v or 3.3v?
Nice.

I don't think we can do that for two reason: 1) it would take a MAJOR re-routing of power around the board (doable, but a LOT of work), and 2) we use the UNO bootloader which is designed for 5v. There may be a problem switching the power to the processor (which controls IO voltage) to 3.3V.
That said, we'll look into it. We're on Rev F of the HC-8+ which means we're always willing to make improvements.
