I guess I haven't made myself clear yet. I would like to use some (3) joystick buttons to turn on/off three sets of led displays that use 12volts. I know I could use 3 spike relay modules but that seems overkill. (But it may be the only way it's permitted.) The DIO's only drive miminal current at 5 volts I think. I would have to have a custom driver from that to switch the 12 volts . That would be more reasonable but is it permissible?
