Why we need high PWM for the pixel led strip?
Why we need high PWM for the pixel led strip? When we learn the IC chip specs, we always note there are two important rates, one is named refresh rate, another important parameter is PWM rate. These two above rates can be important in certain venues, such as broadcast activity. Considering on there are many version IC chips for LED series products like UCS2904,WS2812b, APA107, HD107S,DMX512 etc, today let’s talked these two rates concepts in context. Refresh rate can be a confusing [...]
