Buying Guide
- Display resolution and density: Higher resolutions (like 128×32 OLED) provide crisper text and more detailed graphics, but may require more power and wiring complexity. Lower-resolution modules (32×8, 64×32) are simpler for scrolling text and basic icons.
- Driver architecture: MAX7219-based modules are popular for easy control, chaining, and broad compatibility. Ensure your microcontroller supports the voltage and logic level (5V or 3.3V) you plan to use.
- Power requirements: LED matrices can draw significant current, especially bright RGB panels. Plan for adequate power supply and consider current-limiting if needed.
- Expansion possibilities: Chainable HUB75 or multiple FC16 modules enable building larger displays. Check input/output headers and compatibility with your controller.
- Interface and wiring: SPI/I2C interfaces on small OLEDs simplify wiring. For beginners, modules with clear tutorials and example codes reduce setup time.
- Price and availability: Availability can vary; consider kits that include drivers and headers for faster prototyping, particularly in educational or maker spaces.
- Use-case fit: For text-heavy displays, 128×32 OLEDs and 32×8 matrices with scrolling are ideal. For colorful images and animations, RGB matrices offer vivid visuals but may require more power and control complexity.
