Adjacent to the bind pushbutton is a voltage regulator IC. It is the large three legged transistor like device. I didn't check it with a voltmeter though. I just assumed it was a 5v regulator IC like the 7805 types.
So it looks like it regulats down to 5V and operates off that. I wonder if that means that the issues of operating of NiCd/NiMh are actually irrelevent, as it takes the voltage straight down to 5V so diference between 12V and 9.6V from the batteries is moot? Or is the full battery voltage used elsewhere?
Interesting that the wires are still in yours - mine was the 4 channel no brain one from HC, was yours the 6 channel PC programmable one? Wonder where the wires go?
