If you want for your own experiments to order MPDMv3 bare PCBs only, you can also do it directly at the PCB House:

Soldering process is as simple as 1-2-3, most of the parts are big thru hole ones. Just a 5 minutes soldering fun :)

For testing without connecting the MAINS line and Load, just solder also the LED1. It has no role in the dimming process, just a good testing and "debuging" tool :)

Don't forget about the Heatsink for your Triac. If you stay, and mostly of you will stay, under 50-80W then probably will be no big need. Check carefully your Triac datasheet and adjust accordingly with your needs. The one in the picture beloow is just and example! Do your math please.
