Feature Highlights: 1. Complete DIY Kit – Includes 64 0805 SMD LED display units with row-and-column scanning, capable of showing any 64-pixel character or pattern. 2. Pre-Programmed Microcontroller – Comes with a pre-loaded chip that automatically plays a light animation when powered on. 3. Dynamic Boot-Up Display – Starts by lighting up line by line, then flashes the full screen twice, displays "You're Good" in sequence, and ends with a blinking heart three times. 4. Customizable Content – Easily change what’s displayed by connecting control signals to JP1, without needing to resolder the MCU. 5. Clear Circuit Design – Centered around microcontroller U1, which drives the display through U2–U5 for stable, controlled pattern output. Product Details: This DIY electronic kit is perfect for advertising displays, number/character shows, and soldering practice. It uses a scanning method to control 64 LEDs, allowing you to create custom pixel graphics. The pre-programmed MCU runs a ready-made light animation upon startup, but you can also customize the display via the JP1 port. The circuit is designed with test points (J1–J6) for easy measurement and expansion. Powered by 4–5V, it’s ideal for electronics enthusiasts looking to learn display technology or improve soldering skills. Specifications: - Color: Black - Material: PCB - Power Supply: 4–5V DC - Display Type: 64 SMD LED Matrix (0805) - Control Method: Row/Column Scanning - Package Includes: 1 × DIY Kit (all necessary components) Note: This is a DIY kit, not a finished product—assembly and soldering are required.
