Hard to fight the Chinese on their quantity board pricing. I can't even buy the components on the board for what they make the board AND ship it to the US for!

FWIW, I'd check the ratings on this module. I have those and I believe they have a 23V maximum voltage rating. You can easily exceed that with 18VAC feeding a diode and cap. I blew a couple up using them in a TMCC project and shifted gears to a slightly larger footprint one with 28V max ratings.
