The EZ-0007 is an evaluation board with a built-in uPD168804 constant-current driver IC for LEDs. The board has a built-in high-brightness LED and power regulator, and is able to evaluate lighting by connecting a single 12 V power source. A connector capable of PWM signal input can also be used to connect to an EZ-0006 or other board, and evaluate dimming using a microcontroller.
