Post: Looks like I'm in business now. I ordered two new IO Pi Plus 2.0 boards, soldered in both 40-pin headers and four 20-pin angled headers on the data bus pads, put solder bridges on both of one card's bus address "1" pads, removed the solder bridge from both cards' "link" pads, and soldered some color-coded power leads.into both cards' "5V/GND" pads. I stacked 'em on the RasPi board, hooked up the power leads to the 5 volt bus, and fired the machine up. ([i]Actually, I did one card at a time, trying it wiith the power link still intact so I could draw power off the RasPi, just to make sure. ...didn't want to repeat my earlier errors and fry anything.[/i]) Running [pre][code]sudo i2cdetect -y 1[/code][/pre] gave the hoped-for responses. The completed installation detects i2c addresses 20, 21, 22, and 23. Thanks very much for your help, Andrew. I've got a fighting chance, now. My next step will be to hook up the ribbon cables to the relay cards and see if they work okay. Hopefully I didn't fry them like I did the other cards. I'll start a different thread, just in case anyone might benefit from my further adventures. As I mentioned, hooking up 20-wire ribbon cable to two ten-pin relay cards requires taking a few liberties with the cable and pin sockets, plus writing a bit of C code. Cross your fingers!
