The net server description specifies 9 volts as the supply, and I want to use 12 volts (my bench supply is a small 12v accumulator). As far as I can tell by inspection (without a circuit diagram), the entire board is powered through the regulator, which is a 7805 and thus effective up to 35 volts (subject to dissipation, which is protected anyway). If the reg were to get hot I could always add some fins.
Is there any reason why I could not use 12 volts? I would normally give it a go but this item is too costly for that and there might be a sneaky track in the board that I have not spotted!
