Ahem, let me make a simple judgment on my understanding between the two!
The first choice, XT1506S (SK6822) is an intelligent externally controlled lamp bead from Jixin Technology with breakpoint resume transmission.
Of course, WS2813 is also the so-called breakpoint resume transmitter.
SK6822 lamp bead product overview and characteristics:
1.
SK6822 is an intelligent series-parallel cascade control circuit and light-emitting circuit. Externally controlled LED light source. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a power supply voltage stabilizing circuit, a built-in constant current circuit, and a high-precision RC oscillator. The output driver uses patented PWM technology to effectively guarantee the color of the light in the pixel. High consistency.
2.
Data adopts two-wire transmission mode (DATA1 and DATA2), with the ability to resume transmission at breakpoints, and a built-in signal regeneration circuit, which enhances the cascade signal driving capability. It is recommended Use twisted pairs to increase the transmission distance; connect decoupling capacitors in parallel at the VDD and VCC terminals of the IC power supply to enhance the ability to resist interference; connect DATA2 and DOUT1 in parallel and connect a resistor in series to prevent product signal reflection interference;
3.
Built-in ring oscillator (800MHZ) supports uninterrupted FREE-RUN modulation output to maintain picture stillness; it has a breakpoint resume function and does not require writing address codes;
This is very neat and complete information that we can get by searching for SK6822.
However, the WS2813 lamp beads we searched on Baidu completely lacked the information that should be included in a breakpoint resume transmission. Even the genuine version only has messy specification information, and some of the content is completely copied from WS2812, with many mistakes. What can I do? Let the public use it with confidence?
I have to say that the SK6822 breakpoint resume lamp beads of Jixin Technology are among the best! ! !
