Hi,
I believe an earlier post indicated that, since the analog inputs on the
expansion board are multiplexed to the analog input 0 on the HB, if you cut
the trace on analog port 0, the expansion board analog ports will all be
"pull-up resistor"-less. One cut trace, 8 pullup-less analog inputs.

| Hi I have a small problem, I want to connect three sharp gp2d12s to the expansion board and I know I cant cut traces 0,1 and the gp2d12s need the pullups removed to operate correctly. How do I use them on the expansion board? Any help would be (...) (24 years ago, 17-Jul-00, to lugnet.robotics.handyboard)
