A Feather board truly comes alive with FeatherWings! Introducing the NeoPixel FeatherWing, a fantastic 4x8 RGB LED add - on for every Feather board. With our Feather Stacking Headers or Feather Female Headers, you can easily attach this FeatherWing on top or bottom of your Feather board, making it stand out like a peacock at a rave. These 32 RGB LEDs are incredibly bright and configurable. Arranged in a 4x8 matrix, each pixel can be individually controlled, and you only need one pin to manage all the LEDs. There are jumpers on the bottom to connect the DIN line to any I/O pin on a Feather. It's compatible with all our Feather boards! You can even cut the default jumper trace and choose your own pin. Note that for the Feather Huzzah ESP8266, you should move the default pin, perhaps to pin #15. Currently, due to a NeoPixel timing issue, it works with but isn't ideal for the ESP32 Feather when controlling more than 30 pixels. To get started easily, the LEDs are powered by either the USB or battery power line, whichever has a higher voltage. Two Schottky diodes handle the power switching. This setup can handle 1 Amp of constant current and maybe 2A peak, perfect for creating colorful effects rather than a flashlight. A level - up shifter converts the Feather's 3.3V logic to the power line voltage. If you want even more blinky action, you can chain these FeatherWings together. For the second one, connect the DIN to the first Wing's DOUT, and use an independent 5V power supply to avoid overloading. Check out our tutorial for pinouts and usage details. Our detailed NeoPixel Uberguide has all the info you need to use NeoPixels in various forms, including ready - to - go library and example code for multiple Arduino models.
Using the NeoPixel FeatherWing is easy. First, use the Feather Stacking Headers or Feather Female Headers to attach it to your Feather board, either on top or bottom. You can then control the 32 RGB LEDs. Just connect the DIN line to an I/O pin on the Feather using the jumpers on the bottom. You can cut the default jumper trace and choose a different pin if you want. For the Feather Huzzah ESP8266, move the default pin to pin #15. Remember, it's not the best for the ESP32 Feather when controlling more than 30 pixels due to a timing issue. The LEDs are powered by either the USB or battery power line. The power setup can handle 1 Amp of constant current and a 2A peak, so use it for colorful effects rather than as a flashlight. If you want to chain multiple FeatherWings, connect the DIN of the second one to the DOUT of the first and use an independent 5V power supply. Check our tutorial for pinouts and usage. Also, refer to our NeoPixel Uberguide for library and example code. Keep it away from moisture and excessive heat, and it'll last you a long time.
