An all in one board for driving neopixel, or equivalent, led strips using an Arduino Nano
WARNING: THIS BOARD IS 5V ONLY. APPLYING A HIGHER VOLTAGE WILL RESULT IN A DEAD ARDUINO AND LEDS
Instructions for the jumpers on the back
Adafruit recommends putting a 470 ohm resistor in series with the WS2812B data line. To acomodate both LED and GPIO signals, the back of the board has a resistor footprint and a solder jumper for each exposed DIO. Populate the resistor for DIO that will drive an LED signal, and solder the jumper for DIO that will be GPIO.
Assembly
- Populatate the resistors and jumpers on the back as needed
- Install the arduino
- Attach wire or headers for Vin and the DIO
- Install the capacitor
