## Description

<iframe width="560" height="315" src="https://www.youtube.com/embed/5tKsoqv5BOQ?si=p6kDivwQo5FeG1jm" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>

I have RGB LEDs in just about every form they come: strips, strings, rings, discs, etc.  I constantly seek new and novel forms.

The WS2812C-2020 each only consume a maximum of 15mA, and that's at 100% brightness, solid white color.  That's 3.42A for all 228 combined. They are incredibly bright, and I usually only run them at about 25% brightness.

It has solder pads on the back that match the pinout of the [QT Py by Adafruit](https://www.adafruit.com/?q=qt+py), or [XIAO by Seeed](https://www.seeedstudio.com/catalogsearch/result/?q=xiao). It can be used by any microcontroller via the 5V, GND, and Data In pins. It also has a Data Out pad, for connecting more LEDs on the same data pin.

The six mounting holes are surrounded by capacitive touch compatible pads. They're connected to the A0-A3, A6 & A7 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins.

** Case Options **

The open case is built with 3mm black LED acrylic diffuser and back plates, black nylon M2 standoffs, and M2 screws. Available as kit or fully-assembled.

**Specifications**

The "Fully Assembled" option requires, but does not include, a USB-C cable and power source (USB port, AC power adapter, battery pack, etc).

If the "Fully Assembled" option is not chosen, these parts are **not included**, but are required to assemble and use:

- Microcontroller (Arduino, ESP8266, ESP32, etc)
- Wires, connectors, crimp tool, etc.
- Soldering iron, solder, etc.

Parts I used in my builds:

- [QT Py by Adafruit](https://www.adafruit.com/product/4600)(https://electromage.com)
