Description

I designed this small PCB to help test addressable LED strips. It can also be repurposed for simple portable projects like wearables, since it's very small and lightweight and the usb-c connector allows it to be powered by a cheap power bank.

My website has a page with a more detailed explanation of the project and the design files and firmware are available on the ws2812 tester github repository.

Here's a video of it in action:
