APA102-2020 single LED Board [ available ]

A board with a single APA102-2020 LED. The LED is very useful for status displaying, especially when using multiple RGB LEDs. No matter how many LEDs are used in the system, it requires only two pins to control them all. A serial data signal and a clock signal.

Arduino users can use the “FastLED” library to control this LED.

A very helpful investigation I have found here in the link to Tim’s Blog:

APA102-2020 64 LED Matrix [ obsolete ]

A board with 64 (8×8) APA102-2020 LEDs in 120 x 120 mil grid spacing.

This board is obsolete since the WS2812B was available in 2x2 mm package. But I will remain it online, at least for a while.

WS2812B-2020 64 RGB LED Matrix [ available ]

A board with 64 (8×8) WS2812B-2020 LEDs with 120 mil grid spacing. This is the new version of the 64 RGB LED board. It uses the WS2812B-2020 LED instead of the APA102-2020. It also can be tiled together maintaining the same grid. The footprint is also 2×2 mm, the LEDs can be controlled by a single wire instead of 2.
