KS0370 EASY plug 2812 2x2 Full Color RGB Module (Black and Eco-friendly)
1. Introduction
EASY plug 2812 2x2 full color RGB module is a smart external control LED light source that integrates control circuit and lighting circuit.
Each LED has the same appearance as a 5050 LED bead, and each component is a pixel point.
The pixel point includes an intelligent digital interface data latch signal shaping and amplifying driving circuit, as well as a high-precision internal oscillator and a 12V high-voltage programmable constant current control part, which effectively ensures that the color of the pixel point light is highly uniform.
The data protocol adopts the single-line return-to-zero code communication mode. After power-on and reset the pixel point, the S pin receives the data transmitted from the controller. And the 24-bit data are extracted by the first pixel and then sent to the data latch inside the pixel point.
LED has advantages of low voltage drive, environmental protection and energy saving, high brightness, wide scattering angle, good consistency, ultra low power, long life and so on.
You can easily connect it to EASY Plug control board for communication using a RJ11 cable.
Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.

// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)

// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across

// and minimize distance between Arduino and first pixel. Avoid connecting
// on a live circuit...if you must, connect GND first.
