Description:

Dual voltage power supply designed to be attached to your breadboard or soldered to your next PCB design (the two left GND jumpers provide physical support).

Features:

 - 3.3v and 5v DC output with power LEDs for each

 - Both 5v and 3.3v voltage regulators are 5A rated

 - With the exception of the male header pins and test points, all discrete components are SMT with a minimum size of 1206 for easier hand soldering

Power Input:

 - 2.1mm DC barrel jack: input 7v to 12vDC

Power Output:

 -  3v3 DC and 5v DC to a 'split' breadboard as shown in the v3.0 adjacent video

 - Output current limit is up to 5A regulated by LM1084ISX and LM1585

v4.1 Features:

 - Separate 5 amp voltage regulators

 - Larger input polarity protection diode

 - On/Off switch problem fixed

 - 3 test points

 - 2 grounded mounting holes
