RGB LED MODULE SMD KY-009

From the shop's description

RGB LED MODULE SMD KY-009 The KY-009 RGB Full Color LED module emits a range of colors by mixing red, green, and blue light. Each color is adjusted by using PWM. Compatible with popular electronics platforms like Arduino, Raspberry Pi and ESP32. KY-009 SPECIFICATIONS This module consists of a 5050 SMD LED and 4 male header pins. Use with limiting resistors to prevent LED burnout. Operating Voltage 5V max Red 1.8V ~2.4V Green 2.8V ~ 3.6V Blue 2.8V ~ 3.6V Forward Current 20mA ~ 30mA Operating Temperature -25°C to 85°C [-13°F ~ 185°F] Board Diemsions 18.5mm x 15mm [0.728in x 0.591in] CONNECTION DIAGRAM Connect the red pin (R) to Pin 9, the green pin (G) to pin 10, the blue pin (B) to pin 11 and finally the ground pin (-) to GND. You must use resistors between the board and the Arduino to prevent LED burnout.
