Hi everyone!

I've been hard at work designing up the PCB for ESPLux! I have sent the first revision off to OSHPark for fab, hopefully I haven't missed anything. I am really glad that I made the breakout boards in the first place, they made creating the board schematic much much easier. I have built it up in Kicad, the sources for the board are all over on the ESPLux GitHub page. This was the first time I have used Kicad, it took a short while to get my head around, but hey, I think everything has turned out just fine. I watched a bunch of the Contextual Electronics courses, which helped explain it all quite a lot! Thanks Chris Gammell! I thought that I would have a play around with the BMP to silkscreen option, looks kinda neat!

Hopefully I have enough room around everything for heat dissipation. I have put the rectifier close to the edge of the case, hopefully I can get a heatsink that makes up part of the side of the case.

I have most of the parts in my parts bins, I will probably have to look at buying some more ESP's soon, and I only have one switchmode regulator left, so I'll need to grab some more of them.

While I am waiting for everything to turn up, I think I will start working on the web pages that you can switch the lights on and off from. I still haven't got a 3.3v FTDI cable available, and I am not super keen to use my 5v one, despite people saying that it works just fine.

Here is a render of the board:
