The 8×16 LED Matrix Module is an I2C-controlled dot matrix display designed for the BBC micro:bit. It can display numbers, letters, symbols, and scrolling text, making it ideal for adding visual output to micro:bit projects.
The module connects via the I2C bus for simple two-wire communication and supports three configurable hardware address bits, allowing multiple modules on the same bus.
Key Features
- 8×16 LED Matrix – 128 individually controllable LEDs for text, numbers, and symbols
- I2C Interface – Simple two-wire connection via standard micro:bit I2C port
- Configurable Address – Three hardware address bits for multi-module setups
- Scrolling Display – Supports vertical and horizontal scroll-display modes
- High Brightness, Low Power – Bright LEDs with efficient power consumption
Ideal For
- BBC micro:bit projects requiring visual output
- Scrolling text displays and message boards
- STEM and classroom activities
Package Contents
- 1× 8×16 LED Matrix Module
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- 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.
