This is a great opportunity to showcase the [Wemos D1 Mini ESP8266 LED & Level Shifter Mini Shield], 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 is a fantastic mini Wi-Fi development board based on the ESP8266, perfect for development of addressable RGB LED art projects like my 6.5ft Rainbow Tree. This shield is a smaller version of the full size [Wemos D1 Mini ESP8266 LED & Level Shifter Shield Case], designed to make it easy to add addressable RGB LEDs to your project. The shield includes a 74HCT125 level shifter, one of the most well-regarded high speed level shifters available. 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, supporting parallel output by the fantastic [FastLED library]. 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.
