Matrix RGB LED Module

MATRIX RGBLED GPIO or PWM input, 3.3/5V, LED lightness controllable via PWM Small 2.54 mm pitch pin-header PCB Dimension(mm): 16 x 24 The Matrix-RGB LED is a RGB LED module. It has a 2.54mm pitch pin-head-er in which 5V is power supply, GND is ground, and R,G,B are connected to the LED' s red, green and blue pins. The inputs to Pin R,G and B can be either GPIO signals or PWM signals. The signal level can be either 3.3V or 5V. When the inputs to Pin R, G and B are high the LED will be the brightest. When the inputs to Pin R, G and B are low the LED will be completely off. When the inputs are PWM signals the LED's bright-ness can be controlled by controlling the PWM's duty cycle.   Features Pin Spec S GPIO V Power supply 5V G Ground
