8bit 5050 Full color RGB LED module ME166
28bit 5050 Full color RGB LED module
ME166
Interface:
• VCC: connect to DC5V • G: connect to GND • DI: connect to data input
Features of single LED:
anti-reverse protection circuit, the reverse of power supply will not damage the internal IC of the LED. IC control circuit and LED point light source uses the same power supply.
control circuit and the RGB chip are integrated in a 5050 SMD component, forming a complete control of pixel point. Built-in signal reshaping circuit, signals received will be wave-reshaped first and then output to the next driver, ensuring wave-form distortion to not accumulate. Built-in power on reset circuit and power-down reset circuit.Each pixel of the three primary color can achieve256 brightness display, completed 16777216 color full color display, scan frequency no less than 400Hz/s
Serial cascade interface, via a signal line to complete the reception and decoding of data.
When transmission distance between two arbitrary points is no more than five meters, no extra circuit needed. When the refresh rate is 30fps, cascade number no less than 1024 points. Data sending speed can reach 800Kbps.The color of the light is highly consistent, cost-effective.
Advantages:
1. LED with built-in IC is brighter than common LED 2. High consistency of RGB chips for all LEDs 3. Reliable performance of built-in driver IC 4. Use hard plastic for packaging, prevent press damage 5. Relatively low cost with quality ensured

It is assumed that users have adequate soldering skills and troubleshooting skills to assemble the DSO138 kits. We don’t guarantee that you can get a working deice in the end. But we make as much efforts as we can to help you approaching that goal.
Each main-board has been tested to ensure no short or open on MCU soldering. Each LCD board is also tested to verify soldering is good and display is functional. However, all the rest components are provided with good quality.
