Anyone seen an A/D & Digital input board that will fit into a PDAs compact-flash or secure-digital card slot ? Only needs a few channels for my needs - read a couple of pots, a couple of switches.
There's probably an external USB device, but I'd rather plug-in to a card slot so everything would be "all in one". PDA serial ports - FORGET it, every model seems to have a proprietary power/data/whatever plug on the bottom.
