The NeoPixel FeatherWing adds a 4×8 matrix of 32 individually addressable RGB LEDs to any Adafruit Feather board. Using Feather stacking headers or female headers, the wing connects directly on top or bottom of your Feather for a compact, colourful display.
Only one pin is required to control all 32 NeoPixels, with configurable jumpers on the underside to select any I/O pin. A built-in level shifter converts 3.3 V logic to the power line voltage, and dual Schottky diodes automatically switch between USB and battery power. Multiple wings can be daisy-chained via the DOUT connection.
Key Features
- 32 RGB NeoPixels – 4×8 individually addressable LED matrix
- Single-Pin Control – Default jumper selectable; cut trace to reassign to any I/O pin
- Level Shifter – Converts 3.3 V Feather logic to the LED power voltage
- Dual Power Source – Automatic switching between USB and battery via Schottky diodes (up to 1 A continuous, ~2 A peak)
- Chainable – Connect DIN of the next wing to DOUT, with independent 5 V supply for additional wings
- Universal Feather Compatibility – Works with all Feather boards
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- DIN
- DIN means data in, the pin where this display receives data from the controller. Connecting DIN to the correct SPI data output pin is needed for the screen to receive pixel and command information.
- FeatherWing
- A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
