Just a quick query:
I presume that there is power taken from the serial port on the back of the Dc when using an SD card reader for dreamshell etc.
My question is: Is the power output the same power/Voltage as a USB connection? I ask as I have a USB powered device that I want to power via the DC using the serial output. If anyone has a schematic of the pin outs that would be great too or just which pins are the power outs.
