We tested APA102/APA102C pixe led, nice product for pixel led display....
Now APA102/APA102C dissapeared....and I saw the SK9822 is similar to APA102/APA102C, but the SK9822 is not an exact clone of the APA102. It adds some interesting features. For example the programmable current source to control global brightness and a non-staggered update. But there are also some drawbacks like the protocol incompatibility and the lower PWM frequency.
so anybody can suggest one new LED to replace APA102/APA102C, but not SK9822.
