PIXIE CHROMA is a dual-5x7 character display for Arduino that can be easily chained to create easy-to-use displays as long or tall as you'd like!
Each PCB features 70 addressable WS2812-compatible RGB LEDs in two side-by-side 5x7 grids that can display numbers and characters. Each Pixie Chroma can be controlled with as little as a single GPIO, and can be chained together to make longer character displays.
Please Note: The Arduino library only supports ESP32 family, ESP8266 or Teensy 3.x chipsets! You cannot use Arduino boards with SAMD, ATmega, or nRF chipsets, for example.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
