Microduino-Color led

The product number of Sensor-Color LED is: MSDL11

Sensor-Color LED is full color LED, adopting single serial cascade protocol.

Only one I/O port can control the RGB color of each LED on the line.

If the power supply supports, it can support the cascade of as many as 1024 LEDs.

Introduction of Sensor Pin

Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx.

Special to Sensor-Color LED sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Digital signal output PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
