Multi-purpose low-cost matrix display

Build a compact, low-cost 32×8 LED matrix display driven by an ESP32 — great for various usecases: from a simple standalone clock to a full feature smart home information panel. This project was designed to be cheap (under $10 for key parts), easy to print, and quick to assemble. The housing is a two-part 3D printed enclosure (front + back) with an optional acrylic diffuser for a clean look. All electronics, schematics and software examples are available in the GitHub repository linked below.
