Product description: Chain RGB - RGB LED matrix 8x8 - UART - M5Stack U218
The M5Stack Chain RGB is a display module with 64 addressable WS2812E RGB LEDs arranged in an 8x8 matrix . It supports individual RGB565 pixel control, group data storage, and fast full-screen refresh using a 64-pixel frame buffer. A built-in ASCII character rendering engine enables text display, and the scrolling function supports both solid color and gradient effects. The module also allows for brightness adjustment and image rotation by 0°, 90°, 180°, and 270° . It is powered by an STM32G031G8U6 , and communicates via UART at 115,200 bps. Two HY2.0-4P connectors enable system expansion with additional M5Stack Chain devices.
Chain RGB - 8x8 RGB LED matrix - UART - M5Stack U218.
The Chain RGB matrix allows you to adjust the brightness of the LEDs, so you can tailor the lighting effect to your specific application.
Main features of the M5Stack Chain RGB RGB LED matrix
- 8x8 RGB LED matrix : 64 addressable WS2812E diodes allow you to create colorful graphics, symbols, inscriptions and animations
- RGB565 control : ability to independently set the colors of individual pixels and group data recording
- 64-pixel RGB565 buffer : enables fast refreshing of the entire matrix content
- ASCII character support : Built-in character rendering engine makes it easy to represent letters, numbers, and messages
- Scrolling text : ability to display scrolling texts of up to 32 characters per module
- Colored Text : Scrolling text can be displayed in a specific color or using gradient effects
- Brightness control : multi-level brightness control allows you to adjust the light intensity to suit your project and environmental conditions
- Image rotation : 0°, 90°, 180° and 270° orientation support makes it easy to mount the module in various positions
- STM32G031G8U6 microcontroller : responsible for operating the LED matrix and communicating with the master device
- UART communication : transmission speed 115200 bps in 8N1 configuration
- Daisy-chain connection : the ability to connect devices in series allows you to expand the project with additional Chain series elements
- Two HY2.0-4P connectors : allow flexible connection of the module with other M5Stack Chain devices
- Compact design : 24 x 24 x 16 mm dimensions make it easy to integrate the matrix into small devices and prototype projects
M5Stack Chain RGB Compatibility and Programming
Chain RGB was developed as part of the M5Stack Chain ecosystem and uses two HY2.0-4P connectors and a UART interface to communicate with other devices in the series. The daisy-chain architecture allows for serial connection of subsequent modules, allowing the matrix to be part of a more complex interactive or lighting system. The manufacturer provides the M5Chain library for Arduino , a programming guide for Chain RGB, internal firmware, and communication protocol documentation, making it easy to create your own software and integrate the module into embedded projects.
The kit includes a Chain Bridge that allows you to easily connect adjacent components using Grove connectors.
M5Stack Chain RGB is perfect for projects requiring colorful display of information, animations and lighting effects.
