Review on 2Pcs Isolated Switching Power Supply Board: Universal AC DC Converter Module 110V 120V 220V 230V to DC 5V 12V (DC 12V 1A Version) by Brian Forbis

This is for: 2 piece AC-DC converter module Universal 110V 120V 220V 230V to DC 5V 12V PowerFirst isolated circuit, no mounting holes. I used a fiberglass board and tie downs to secure it and then some goop along some edges to really secure it. Drill a hole for the 120VAC wires to be soldered to this block and go under the fiberglass board to the 2 pin connector. I covered the 120VAC solder points with goop. I turned on a block that was outputting 12.48VDC with a small load of about 0.15A. I'm going to use it for the Arduino controller and use another small LM317 regulator for 9V (with a 2.5V drop across the regulator seems to work). ). This extra regulator may not be needed, but I prefer 9V, which is below the Arduino specs.
