HD107S 3535 Micro pixel LED Chip
(1) HD107S Smart 3535 SMD integrates high-quality external control double-wire serial cascaded constant current IC, compatible with SK9822/APA102, BUT MUCH BETTER, same control way. some factory indicate it as APA102, or say it is upgrade of sk9822, or named LC8823/NS107S.
(2) Complete external control pixel, make the color mix uniformity and consistency.The default output constant current value OUTR/OUTG/OUTB is 17MA.
(3) Built-in power-on reset and power-down reset circuits, the light does not light up after power-on.
(4) Two-wire data transmission, unlimited cascading, the maximum serial input data frequency is 40MHz.
(5) No data input, zero power consumption when the light is off.
(6) The PWM refresh frequency is 27KHz.

HD8812 SK6812 WS2812B 5050 Pixel LED Chip Black and White
HD8812 5050 Pixel LED is an intelligent externally controlled LED that integrates a control circuit and a light-emitting circuit. Its appearance is the same as a 5050 LED . Each LED is a pixel, it is same function with addressable pixel 5050 sk6812/ws2812b/lc8812/apa104/apa105/apa109 led, use same pcb design, pin to pin function and same control way. The LED contains an intelligent digital interface data latch signal circuit.Power supply voltage regulator circuit, built-in constant current circuit, data regeneration circuit, high precision RC oscillator, output drive adopts patented PWM technology, which effectively guarantees the color consistency of the each pixel,and the default output constant current value OUTR/OUTG/OUTB is 12MA.
