Here’s a guide on you how to get your 3.3V microcontrollers — such as the Adafruit Feathers, Arduino M0 Pro, and Teeny boards — to control your 5V NeoPixels. Often, a mismatch of logic levels can cause strange behavior, such as dim or wrong-colored pixels — especially on longer wire runs or in projects that use large numbers of NeoPixels powered at 5V. Here comes a logic level shifter to the rescue!
There are lots of great microcontrollers that speak the language of 3v3 (3.3 volts) which can make it difficult for them to communicate with NeoPixel LEDs, which speak 5V. Thankfully, along comes a bi-lingual translator, the logic level converter — or level shifter — to save the day.
