The Adafruit DotStar High Density 8×8 Grid packs 64 individually addressable RGB LEDs into a compact 25.4 mm × 25.4 mm (1" × 1") square. Each DotStar pixel features a built-in PWM driver and is controlled via a 2-wire SPI interface using just two digital I/O pins — data and clock.
Each LED delivers full 24-bit colour with high-frequency PWM for smooth, flicker-free output. The grid includes two 4-pad connection ports on the back for easy wiring, plus a power/ground pad set for an optional 220 uF capacitor. Four mounting holes can be snapped off with pliers for a perfect 1" square form factor.
Key Features

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- 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.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
