Aurora 9×18 mk2 kit
This kit includes everything you need to build Aurora 9×18 mk2, plus mounting screws & nuts. Those screws can also help you when you solder in the LEDs, by giving the PCB a lift off the working surface. The smallest SMD parts are 0603 size, which is quite tiny. Naturally it’s very easy to lose them while assembling. Since it’s not fun having to buy those little parts because you lose them, there are a few extras included for all 0603 size parts. There are a few extra LEDs included as well. Hopefully you won’t have to stop the assembly because you’ve lost a few parts. The diameter of the PCB is 4.32 inches (109.7 mm).
