Multi-purpose low-cost matrix display

SummaryBuild 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.GitHub repo: https://github.com/Smengerl/matrix_displayKey Features32×8 LED matrix (MAX7219 / FC16 compatible) driven by an ESP32Very low bill of materials — total cost under ~$10 (ESP32 + LED matrix panel)Small, snap-fit 3D printed housing with optional acrylic face plateMultiple example usages: NTP-synced clock, Home Assistant display via ESPHome, solar production panelOpen design: STL, schematics, and firmware examples on GitHubExample usage from repo:Standalone NTP-synced clockESPHome in
