This is a case for the [Wemos D1 Mini ESP8266 LED & Level Shifter Mini Shield](https://www.tindie.com/products/9723/), which makes it easy to control addressable RGB LEDs such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, APA102 (Adafruit DotStars), and SK9822. The [Wemos D1 Mini](https://www.aliexpress.com/item/WEMOS-D1-mini-Pro-16M-bytes-external-antenna-connector-ESP8266-WIFI-Internet-of-Things-development-board/32724692514.html) is an excellent mini Wi-Fi development board based on the ESP8266. I've used it extensively in development of addressable RGB LED art projects such as my [6.5ft Rainbow Tree](https://www.evilgeniuslabs.org/tree-v2.html). This is a smaller version of the full size [Wemos D1 Mini ESP8266 LED & Level Shifter Shield Case](https://www.thingiverse.com/thing:2502212) The shield includes a 74HCT125 level shifter, which is one of the most well-regarded high speed level shifter I've found. This shifts the 3.3V logic level of the ESP8266 to the 5V expected by addressable RGB LEDs. These projects often work fine without a level shifter, until they don't. Four digital output pins (D5 - D8) are run through the level shifter. These pins support parallel output by the fantastic [FastLED library](https://github.com/FastLED/FastLED/wiki/Parallel-Output). The shield also includes places for data line resistors as recommended when driving LEDs, especially when powering the microcontroller from the same power supply as a large number of LEDs. Duplicate breakouts are included for each of the Wemos D1 mini pins.
