10X 3W LED Board For Large Bar-Graph Meter/Light Effects

The 10X3W White LED board has been designed to create large size bar-graph meter and light effects generator.  The board contains 3W LEDs, D-Pk MJD44H11 transistor as driver and current limiting resistor across each LED. Circuit works with 5V, each LED take approx. 300mA-400mA current, each LED can be controlled individually by applying TTL voltage, header connector provided to interface micro-controller, Ardunio, Raspberry Pi etc.  . LED dimmer possible by applying PWM signal to each LED, Easy interface with Arduino.
