DC Power Adapter Module

DESCRIPTION

This small DC Power Adapter Module accepts a standard DC power plug such as from an AC adapter and brings the power out to a header for easy hookup to a breadboard.

PACKAGE INCLUDES:

• DC Power Adapter Module

KEY FEATURES OF DC POWER ADAPTER MODULE:

• Accepts standard 5.5 x 2.1mm DC power plug
• Brings DC voltage and ground out to male header
• Power on LED Indicator

Modules don’t get much simpler than this.  This module provides an inexpensive and convenient way to adapt any standard DC power plug to a breadboard such as if you have a 5V AC adapter that you want to use to power your breadboard directly or you want to bring in something like 12V to power a motor driver.

The power and ground are brought out to a 4-pin male header.  There are 2 pins (‘+’) for the power and 2 pins (‘-‘) for the ground which allows you to  double-up the jumper wires if a fair amount of current will be drawn from the module to minimize voltage drop across them.

The power input has a zero ohm resistor in series.  This could be replaced with something like a ferrite bead or diode if desired for some applications.

The on-board LED has a 2.4K series current limiting resistor, so it can safely handle higher voltages.
