Thanks to the HAD prize seed fund, I could afford more PCB !

I ordered more #DYPLED boards in .8mm thickness and white soldermask. And this time I successfully "tented" my vias, which greatly helps with assembly :-)

As previously written, I used Zener-less LEDs. This is clearly indicated in the marks at the back of the module. I'll have to solder a few... Overall, I could solder 44 modules, more than I can use now, so who is interested to get/use some ? Should I open a Tindie store ? :-)
