RG LED Module

From the shop's description

Description The LED RGB 5mm Module incorporates a red and green LED with a clear lens in the same 5mm package. key Features of LED RGB 5 mm Clear LENS Module: RGB (Red/Green) 5 mm LED Water clear lens The LED is a common cathode type which means all 3 of the LEDs have their cathodes tied together. The cathode is connected to the ground and the red, and green LED pins should be connected to digital or PWM output pins. The LED housing is clear, so the LED output is quite bright when viewed straight on unless PWM is used to lower the brightness. Module Connections There is a 3-pin header on the assembly for making connections. 1 x 3 Header GND / – = Ground G = Green LED anode. Connects to digital output/PWM pin on uC. Active HIGH R = Red LED anode. Connects to digital output/PWM pin on uC. Active HIGH Technical Specifications: Maximum Ratings Vcc 5V I Max Maximum Current Draw per LED 20mA Operating Ratings Voltage Drop Red LED 1.8-2.4V Green LED 2.8 – 3.6V Polarity Common Cathode Dimensions L x W (PCB) 18.5 x 15mm
