HD107S is a type ic for the three-color RGB Diming control strip and string, This ic using the CMOS process to provide three-color RGB LED output driver to adjust the output with 256 grayscale and 32 brightness adjustment, with 2 signal output way, one is clock , another is data, the clock and data are synchronized, so that the crystal cascade piece of output movement is synchronized.

HD107S 5050 Digital LED Features: 

1. HD107S with transmission rate 40MHz

2. PWM refresh rate>27KHz (APA102 with PWM frequency 20KHZ, APA107 with 9KHz, SK9822 with 4.7KHZ,)

3. HD107S LED with a much lower voltage drop than APA102/SK9822 LED, but higher brightness

4. HD107S LED is with the same protocol as APA102

5. HD107S with a larger lighting beam angle

6. Copper bracket and gold wire to keep a good heat dissipation

7. Choose positive output or negative RGB three-color LED output 256 grayscale(8bit) and 32(5bit) level brightness adjustment

8. With self-detection signal build in support for continuous oscillation PWM output, can be maintained static screen
