The BeagleBone uses 3.3V on the expansion headers, so for building a breakout setup you would probably want to include some level conversion kits to convert that to 5V (and for isolation). Adafruit has a nice selection of addons for the BeagleBone:
http://www.adafruit.com/category/75 I personally use the BeagleBone A6 ($89) + 8 channel logic converter ($8) + Adafruit Proto Plate ($7.95) for prototyping, and the Proto Cape ($9.95) for more long term designs. The BeagleBone ships with the 4G SD card, you still need to buy a good quality power supply such as the 5V 2A supply that Adafruit sells for $9.95. The BeagleBone can be powered with either USB or 5V barrel connector; but the USB interface is limited to 500mA of current so a 5V supply is preferable. ________________________________________ From: Charles Steinkuehler [[email protected]] Sent: Wednesday, February 06, 2013 10:23 AM To: EMC developers Subject: Re: [Emc-developers] BeagleBone question -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 2/6/2013 8:08 AM, Gene Heskett wrote: > On Wednesday 06 February 2013 08:58:45 Charles Steinkuehler did > opine: Message additions Copyright Wednesday 06 February 2013 by > Gene Heskett > >> There are a *LOT* of I/O on the BeagleBone vs. a parallel port. > > Thats much better.

Bas has designed the BeBoPr board, as others have mentioned. I purchased one from him and actually have it in-hand, although I'm not yet to the point of hooking it up (I'm still watching pins twiddle on the 'scope). There is also another cape being designed that just won the BeagleBone Cape Design Contest: The Replicape: http://beagleboard.org/CapeContest/winners/ Both of these are geared towards driving a 3D printer, but on the BeBoPr at least, there is a header that brings out the step/dir and enable lines for hooking to a beefier stepper driver than is typically used for the 3D printers. A breakout card hooking the BeagleBone I/O signals to more conventional DB25 connectors with some buffering and protection is a fairly trivial exercise. I'll do this if it comes to it and no one else beats me to it, but first the 'Bone needs to turn into a useful platform for LinuxCNC.
