First light for my LED modules! I’ve settled on all the parts and designed the PCB. The picture above shows the very first PCB module operating. 27 more of these and I’ll be ready to grow lettuce. Well, I still need to buy dirt ;)

You can see the 0.1″ thick traces in this photo as well as the barrel adapter that delivers power to the module. I need the thick trace since this is the only module that will have a barrel connector. I’ll link all the other modules to this one via the screw terminals. As such I need to make sure this module has the trace widths needed to carry 2 to 3 amps of current.
