WS2812 FPV tail light and light bar

tb A tail light costs 5 yuan, and shipping is not included. It’s not cost-effective! ! !
TB four light strips cost 28 yuan,~~This is not a money grab! ! ~~
So I drew this board, including **3** taillights and **8** light bars, ~~Ultimately making use of the 10x10 free area~~
Taillight size: 2.4x1.5cm
Light bar size: 0.5 x5.25cm
Because there is an extra fee for other ways of joining the boards, you need to cut this board by yourself
! All DRC errors are ignored when generating gerber, and the line has been tested without any problems!
