EB004 LED Board Block Diagram

* Click EB004-30-2 for the datasheet. * The male D-type connector fits into the Female connector of one of the ports of an upstream board. * LED D0 and its series resistor R0 will be connected to pin 1 of the Male D-type connector * The series resistor is here to control the current that will flow from PICmicro to the LED. ** A LED usually has an Imax of 20mA ** The PICmicro has an Imax of 25mA (sink or source) ** The LED has a Forward Voltage drop of 1.7V ** In this case the 560 Ohm resistor will limit the current at: *** (5V-1.7V)/560 Ohm= 5.9mA *** This is well under the current limits of both PICmicro and LED * The Female connector is here to connect several boards in parallel. Be ware of the total current limit of the PICmicro if you do so. (:nl:)(:table style="clear:both":)
