Thanks for the notes, I checked here last night before continuing and there weren't any answers so I forged ahead...here are the results.

I am using the recommended 12V power supply with the PDB, so it has enough power to run everything so far.

Using the PDB, I pulled 5V straight into the SX Key. I ran the OSC1 and OSC2 to the SX chip and had the SX and other chips on the PDB running at 3V (I wired in a regulator for the 3V).

Everything seems to be working fine. I hooked up the USB Oscilliscope and watched the volts to make sure I wasn't getting any unexpected results.

If I have time tomorrow, I'll drive up and buy a SX Key Ring and do it properly. Would you recommend I stop doing development until then, or does it sound like I can keep going?

Thanks again,
Dan
