@Taz79 said in Can SG-1100 running on 12V battery supply?:
It would be fun to know what voltage tolerances the SG-1100 board could handle though (due to design).
13V
The Z-Diode at the input limits it. Then there's the 470µF/16V capacitor in parallel.
See page 6 in the schematics (this is a v5 schematic, SG-1100 is v7, though)
I'd use something like a 1N5400 diode in front of the device. That can handle 3A and has a forward voltage (drop) of 1,0V to 1,2V.
The board itself has "Less than 1W thermal dissipation at 1 GHz". That's as much as you'll have on the 1N5400 alone... or damn effective.
