Anyone have any tips/tricks?

I’m curious to know what you are using this for? It looks like WS2812b?

Where is the capacitor? Every pixel needs a cap. Check these out from RayWu:

Ws2812b , My plan is to daisy chain them every 3 or 6" should be 18-36 pixel depending on size and spacing. Im going to run a attiny85 and put everything in a hula hoop.

@Jon_Burroughs Its on the bottom :slight_smile:

You can make it smaller by putting the labels on the inside. One ‘V’, one ‘G’, or just ‘+’ and ‘-’, then ‘I’ and ‘O’, then bring the dimension lines in towards the pin holes.

What’s the lone via for? I’d also make a VCC and GND pour so you’re not running actual traces.

And lastly, the last time I did this (for some WS2801), I used smaller holes, and spacing that matches a ribbon cable.

And depending on where you’re sending it to, you can tile it, and cut them out yourself.

If you are sending it as-is, no tiling, then consider rounded corner for your own comfort. Trust me on this. :slight_smile:

Or, if you are sending it to OSHPark, where they do contour cutting, then tile and round the corners. Let me take a picture of the design when I sent it to what was originally BatchPCB but then bought by OSHPark.

I’m going to do some redesigning when I get home from work. I want to place the cap on top and remove the text altogether.

I thought about using ribbon cable but I think I can save weight but using wire.

Been there, done that. Ribbon cable is better. Pictures coming up.

Be interested to know how much price difference is between the above and what you are doing… seems a decent deal?

@Justin_Eastman the design on that one is great IMO … I don’t care for circle design and I also wanted holes for the input/outputs rather then pads.
