APA107LED chip, APA107 compare with APA102/APA102C/SK9822

[Jason Gong]

APA107 is the best choice to replace APA102/APA102/SK9822
Next step, we will upgrade the APA107 with high PMW to reach 26-28Khz, IC named "NS107S"

Below is our 's test result for APA107 LED,

“As we measured: This is what we found out:
The red led is less bright, so the RGB balance is now more ( green-blue) than before.
The led heats less. !
We think that the logarithmic curve of the APA107 starts more logic in the beginning:
The old led APA102 gave nearly NO intensity in the very beginning. (This gave no nice display)
Now there is some small brightness in the beginning of the APA107 curve. What is very good.”

General Description
APA107 pixel LED SMD is a type ic for the three-color RGB Dimming control strip and string, This IC using the CMOS process to provide three-color RGB LED output driver to adjust the output with 256 grayscale and 32 brightness adjustment, APA107 with 2 signal output way, one is clock ,another is data, the clock and data is synchronized, so that the crystal cascade piece of output movement is synchronized .

Feature
CMOS process,low voltage ,low consumption
Synchronization of two-lane
Choose positive output or negative RGB three-color LED output
8 bit(256 level) color set ,5bit(32 level) brightness adjustment
Build-20ma constant current output
With self-detection signal build in support for continuous oscillation PWM
output ,can be maintained static screen

Application
LED lamp
LED Strip ,led pixel module
LED billboard LED screen

it is a new led in the market? very intersted. I think apa102c and sk9822 is better. because,it is double signal transmission. we supply the apa10c and sk9822 addressable led strip,no matter what led broken,it can work normally.

@Alvin-chan
APA102/APA102C has disappeared....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...
Obviously APA107 is best choice with higher PWM and lowest price.
