    Like this relay board because it's convenient to use, has optical isolation and uses 5 volts for operation. Saves some time and looks better than wiring up a circuit on a protoboard. Has nice mounting holes provided as well. Had some confusion about the "In" pin, determined that it selects the operation of the relay by grounding to the 5 volt minus pin (or just jumpered permanently if not used) . It's used for relay selection when using more than one relay board. I sure would like schematics

    I used 16 of these really easy to use relay boards in a Christmas project and they performed flawlessly. Thank you Bang Good for the easy to use web site.
