|
Hi, I'm working on a project in which I use the handy-board to steer a servo. I noticed that the voltage regulator on my handy-board gets rather hot. You actually burn your fingers on it...

Hi Scott, (...) Since everything's CMOS, there's no trouble with static loading (CMOS inputs require essentially zero current in static operation). You will, however, be increasing the capacitance on the bus, which slows down the transitions a (...) (28 years ago, 21-Nov-96, to lugnet.robotics.handyboard)
