Description
A 7 segment display board consisting of RGB LEDs. The notation is as the conventional notation.
MOSFETS are added for PWM brightness adjustment. The resistors should be selected according to the voltage drop of the LED and operation current.
Listed resistors are calculated to be operating 20mA for each diode, with a constant 5 Volt source.
