UCS8904 Advantages:
- Very High PWM rate 4.0KHZ allows for filming the pixels with 60fps appromately.
- Drive 4 colors LED allowing for tones that were previously hard to achieve with single RGB strip.
- 16 bits of data, 65536 grayscale for each color makes dimming curves very smooth.
- High PWM 4.0KHZ rate allows for filming these pixels with cameras up to 60fps
- RGB and White ( any other single color) can be independently controlled to allows us to create bolder and more vibrant colors than with RGB alone.
UCS8904 Shortcomings:
- No Clock data line, only data line restricts refresh rate to be limited by the protocol speed, which will generally be slow.
- No redundancy in data like the GS8208.
UCS8904 Cautions:
- Very Similar with the SK6812 RGBW Protocol / SM16704 Protocol, but couldn't work together with those IC chips.
- Similar with the UCS2904 IC, but couldn't use the UCS2904 IC program to work with this UCS8904 LED strips.
- UCS8904 have same pin define with the UCS2904 that they're available for same PCB, but BOM maybe a little different.
- UCS8904 chip , couldn't choose the program of the UCS2904. Should be re-programmed.
