Case for Wemos D1 Mini ESP8266 LED & Level Shifter Shield This case is designed specifically for the Wemos D1 Mini ESP8266 LED & Level Shifter Shield, making it easy to control addressable RGB LEDs such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, APA102 (Adafruit DotStars), and SK9822. The Wemos D1 Mini is a top-notch mini Wi-Fi development board based on the ESP8266, which I've used extensively in my addressable RGB LED art projects like my 6.5ft Rainbow Tree. I attached the PCB to the enclosure using M3 socket cap screws, both for mounting it to the enclosure and attaching the lid. The length of the screws can be adjusted according to your needs, with options ranging from 4mm to 6mm, or even longer for additional stability. To ensure versatility, I included holes in the enclosure that allow you to easily attach it to a pole or other objects using zip ties. This feature provides endless possibilities for creative projects and installations. The shield boasts a robust 74HCT245 level shifter, widely regarded as one of the best high-speed level shifters available. Its primary function is to convert the 3.3V logic level of the ESP8266 into the 5V expected by addressable RGB LEDs, ensuring seamless communication between components. Four digital output pins (D5 - D8) are routed through this level shifter and support parallel output via the fantastic FastLED library. This feature enables users to create stunning visual effects with ease. In addition to its numerous benefits, the shield also features places for data line resistors and a large 1000uF capacitor, both of which are recommended when driving LEDs, especially when powering the microcontroller from the same power supply as multiple LEDs. For added convenience, duplicate breakouts are included for each Wemos D1 mini pin, allowing for easy access and manipulation. Lastly, the shield includes a dedicated spot for easily adding an IR receiver, further expanding its functionality and potential uses.
