    Exactly. I am looking for one that holds 2 or 3 AA’s.

    Can I power a 12 volt 500 ma solenoid coil with this opto-isolator board? I broke out both my voltages from an 8 AA cell battery pack. I’m using 3 volts on the input side (2 AA’s), and 12 volts for the solenoid (8AA’s). My input supply side signal is an analog output from a 3.0 volt ATmega328 chip (output A0 ). I have the output side on 12 volts to drive the solenoid coil. I don’t want to fry the output pin of the atmega. If I add a 12 volt relay before the solenoid coil, will that help? Or is this board made to replace that also? I can also add a clamping diode on the solenoid coil if needed.

No public wish lists :(
