<h5>Case for Wemos D1 Mini ESP8266 LED &amp; Level Shifter Shield</h5> <p>This is a case for the <a href="https://www.tindie.com/products/jasoncoon/wemos-d1-mini-esp8266-led-and-level-shifter-shield">Wemos D1 Mini ESP8266 LED &amp; Level Shifter Shield</a>, which makes it easy to control addressable RGB LEDs such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, APA102 (Adafruit DotStars), and SK9822. The <a href="https://www.aliexpress.com/item/WEMOS-D1-mini-Pro-16M-bytes-external-antenna-connector-ESP8266-WIFI-Internet-of-Things-development-board/32724692514.html">Wemos D1 Mini</a> 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 <a href="https://www.evilgeniuslabs.org/tree-v2.html">6.5ft Rainbow Tree</a>.</p> <p>I used <a href="https://amzn.to/2OCwsWQ">M3 socket cap screws</a> to mount the PCB to the enclosure, and to attach the lid. I used 4mm or 6mm long ones, but you could use longer ones if you want to mount the enclosure to something.</p> <p>I also included holes in the enclosure for mounting to a pole or other objects with zip ties.</p> <p>The shield includes a 74HCT245 level shifter, which is 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.</p> <p>Four digital output pins (D5 - D8) are run through the level shifter. These pins support parallel output by the fantastic <a href="https://github.com/FastLED/FastLED/wiki/Parallel-Output">FastLED library</a>.</p> <p>The shield also includes places for data line resistors and a large 1000uF capacitor 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. The shield also includes a spot for easily adding an IR receiver.</p>
