Understanding PCB cost is crucial for effective budget management. Key factors include core materials, board specifications, and design complexity like fine lines and advanced vias. Quality standards such as IPC Class, testing requirements, and especially order quantity also significantly influence the final price, allowing for better project planning and cost optimization.
The image is mainly about the difference between the work principle of WS2812 and WS2813 LED strip. The most obvious difference is: when the led one of the WS2812 was broken, it will affect the other led working, but the WS2813 will not appear above situation.
If you don’t know the WS2812 or WS2813, please allow me to introduce them to you.
Generally speaking, WS2812 has two versions: WS2812 and WS2812B. WS2812B is an upgraded version of WS2812. They are an integrating control circuit and the intelligent external control LED source of the light-emitting circuit, which looks similar to the 5050LED. It internal included intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal
