Breadboard PSU5V & 3.3V Power Supply

Product tags

This breadboard power supply packs the regulators, smoothing capacitors, and some power LEDs into a small board you can easily plug into any breadboard. Unlike some breadboard power supplies, this one sits in the “IC” well of the breadboard. This means it will fit any breadboard, and can provide two different voltages off the same DC input.

It provides easy access to the remaining pins of each row to connect it to any side power rails or any other wires which need to be hooked to either power or ground.

Note: Shipping versions of this board do not have pins soldered to the Ground and +V1 or +V2 outputs as shown in the photos. This is so you can solder pins in the orientation you’d prefer, or solder wires for a more permanent installation.

Specifications

• DC input: 7-19V DC (center-positive 2.1 or 2.5mm barrel jack)
• DC Output: Two fixed configuration outputs, 3.3 and 5V @ 800ma; custom voltages between 1.25-13.8V DC @ 800mA on request
• Two power indication LEDs, one for each DC output
• Protected against reverse polarity DC input
• Outputs are not fused against overcurrent
• All specifications subject to change
