M5Stack Chain RGB Display Node
M5Stack Chain RGB Display Node is a full-color LED dot-matrix display node in the Chain series featuring an 8x8 pixel matrix. This display node supports individual pixel control, batch pixel writing, and high-speed full-screen buffer refresh, enabling smooth and detailed dynamic lighting effects and pixel animations. The Chain RGB display node offers built-in ASCII character rendering and font engine, supporting scrolling string display with freely specifiable colors or built-in color gradient effects. This display node also offers multi-level brightness adjustment and multi-angle screen rotation (0°, 90°, 180°, and 270°), adapting to various installation and viewing angles. The Chain RGB display node is powered by an STM32G031G8U6 microcontroller, and utilizes a UART serial daisy-chain communication protocol and features two HY2.0-4P expansion ports. This display node is suitable for applications such as color pixel light art, desktop ambiance lighting, creative signage, and smart device status indicators.
