The 40 LED RGB Matrix Shield Expansion Board is a smart control LED light source with a stackable design, compatible with Arduino UNO . The control circuit and RGB chip are integrated into a 5050 SMD component. It includes a smart digital data port and a signal amplification relay circuit. In addition, it has an internal precision oscillator and a programmable constant current controller, to ensure efficiency and consistency of the product.
Features
Shield Matrix 40 RGB LEDs
1. Anti-reverse protection circuit, so that the power source will not damage the LED Integrated Circuit.
2. The IC control and LED light source use the same power source.
3. The control circuit and RGB chip are integrated into the 5050 SMD component, forming a complete pixel control.
4. The received reshaping signals are reshaped into 'waves' and then output to the next driver, ensuring that 'waveform' distortion does not build up.
5. The power circuit and reset circuit are integrated.
6. Each pixel of each of the three primary colors can reach a brightness of 256, a full color 16777216, scan frequency of not less than 400Hz/s.
7. It has a 'cascade' serial interface, via a line signal, to complete the reception and decoding of data.
8. When the transmission distance between two arbitrary points is greater than five meters, no extra circuit is needed.
9. When the refresh rate is 30 fps, the 'waterfall' number is not less than 1024 dots.
10. Data sending speed can reach 800 Kbps.
11. The color of the light is highly consistent, and it has great cost-efficiency.
LED Advantages
