Breadboard 1.8V, 3.3V and 5V Power Supply

Breadboard power supply top view.

First of all, we know that we will need one or more of the 1.8V, 3.3V or 5V power supplies so that we can operate our modules, microcontrollers and sensors. First, we designed a module that we could place on a breadboard.

Details

Switch

With the on / off switch on the module, we can turn the power on and off to the output of our circuit. We can supply 6 to 15 VDC voltage to the circuit with two pins (VDC In) or Barrel Jack input.

Power LED

In addition, there is a red LED in the circuit. With this led, we can see that our circuit is open or closed.

In order to give the desired voltage to the output, we need to connect the jumpers in the circuit to the desired voltage pin. For example, if we want 5V at the output, we need to insert the jumper in the middle 5V. 

Power Output

In addition to the pins we can place in breadboard, there are 2 positive (+) and 2 ground (- / GND) outputs in the circuit.

Features

  • Selectable 1.8V, 3.3V and 5V output voltage
