Microduino-Color led

mCookie-Color LED is a colored LED sensor with an built-in IC control chip, which can be cascaded arbitrarily. With only one I/O port, you can control all the lights and each light can be controlled separately.

Sensor Pin Introduction

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.

Feature

• With single bus control. Only one I/O port to control, and complete the receiving and decoding of the data;
• With built-in IC controller, and serial connection interfaces, which can cascade control;
• The three primary colors of each pixel point can realize 256-level brightness display, and achieve 16777216-color whole true color display. And the scanning frequency is not lower than 400Hz/s;
• With ultra-low power and ultra-long life.

Specification

• Sensor voltage
  • 3.3V~5V working voltage

• Size of the sensor
  • Size of the board: 23.5mm*13mm
  • 1.27mm-spacing 4Pin interface connected with sensorhub;
  • CAD drawing of the sensor: File:Sensor CAD.zip
  • 1.27mm-spacing 4Pin interface connected with sensorhub.

• Function description
  • Adopt WS2812 integrated control light source;
  • RGB of each pixel point can achieve 256-level brightness display;
  • When the updating rate is 30 frame/s, the cascade number is not less than 1024;
  • When the transmission distance between any two points is not over 3 meters, don’t need to add any circuit.

• Connection
  • This sensor can be connected to the following interfaces of the core:D2~D13
  • Multiple sensors cascade: Connect the (OUT) of the former LED—Strip to the (IN) of the later Color_LED.
