RGB LED Module

The LED RGB 5mm Module incorporates a red, green, and blue LED with a clear lens in the same 5mm package and includes built-in current limiting resistors.

key Features of LED RGB 5 mm Clear LENS Module:
RGB (Red/Green/Blue) 5 mm LED
Water clear lens
Built-in current limiting resistors

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, green, and blue LED pins should be connected to digital or PWM output pins.

The module has built-in 150 ohm series resistors to limit currents to a safe level, so no additional current-limiting resistors are required.

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 4-pin header on the assembly for making connections.

1 x 4 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
B = Blue LED anode.  Connects to digital output/PWM pin on uC.  Active HIGH
