Short .mp4 Video (click to enlarge)

Description:

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

Features:

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

 - 2 common power input types: DC barrel jack or mini USB

 - With the exception of the male header pins, 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

   or

 - miniUSB: 5vDC

Power Output:

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

 - Output current limit is 1000mA regulated by NCP1117 and NCV1117

v2.1 fixes a problem with the On/Off switch.

v2.1 Features:

- Separate voltage regulators

- 3 test points
