Hi all, I am a young Dutch engineer assigned to build a prototype of a six-legged robot. I am considering to use the handy-board as the controller. There are however a few questions I have.

(...) Is there any current going directly into GND from the LM2931Z-5.0? If so, would this cause any "extra" heat other than from the current the HB draws? -Eric (29 years ago, 16-May-96, to lugnet.robotics.handyboard)

After I slap a Polaroid sonar module onto my robot, I'd like to add some shaft encoders. However, it appears that the shaft encoder routines and the sonar routines both use some of the same ports on the digital headers. Is it possible to use other (...)
