Description
Simple Neopixel LED driver.
WLED Neopixel compatible driver made with Wemos D1 mini V2 and Wemos D1 PRO in mind. Project use quadruple buss buffer (SN74AHCT125DR) as as logic level shifter from 3V3 to 5V to ensure correct voltage level especially when using long cables between MCU and LEDs.
As result you get four channels with 5V logic level.
