Comparison between GS8208 and WS2815 LED

12V WS2815 LED originates from 5V WS2813LED. They all adopt the built-in design of resistance and capacitor, Individually addressable, breakpoint continuous transmission.
12V GS8208 LED adopts similar design of WS2815. and has the function of breakpoint continuous transmission,
12V Individually addressable. But there is no resistance and capacitor inside GS8208 LED. When design circuits, need to design capacitors and resistors externally.
In a word, using WS2815 LED, Save cost and good looks,
GS8208 with external capacitor and resistance, product reliability should be higher than WS2815.

AdrianZH:
GS8208 with external capacitor and resistance, product reliability should be higher than WS2815.
