If you're working with the WS2812B and need to turn corners, you'll want to check out this [NeoPixel Corner adapter PCB from josh.com](http://wp.josh.com/2015/09/12/neopixel-corner-cases-accurate-and-easy-rectangles-with-ws2812b-strips/). It's a pretty simple board. I came across it as a solution for an upcoming lighting project.

In josh's example, he used a [CNC to mill the PCBs](/x-carve-cnc-review.html). If you're using one-sided FR4, that might work well. You'll want to double-check thicknesses if you want to use OSHPark or similar.

You can check out the [full write-up here](http://wp.josh.com/2015/09/12/neopixel-corner-cases-accurate-and-easy-rectangles-with-ws2812b-strips/) or the [NeoPixel Corner Board project GitHub](https://github.com/bigjosh/NeoPixel-Corner-Board).
