Technical Specifications #

The WS2801 pixel protocol was developed by World Semi in China. It is part of the WS28xx series of protocols, which are known for their high refresh rates and flexibility in LED choice.

The WS2801 protocol adds a clock line to the WS28xx series, which allows for even higher refresh rates. The control circuit of the WS2801 protocol comes in a SOP14 package, which provides more flexibility in terms of the LED options that can be used with the protocol.
