The SwitchTrick is a perfect companion for any electronics tinkerer! It is a super easy to use, breadboard compatible variable power supply. With a wide range of flexibility, it takes 3-17V in, and is adjustable from 0.9-6V out at 1A. The SwitchTrick fits on any breadboard, and can be powered by USB, lithium batteries, or anything using a 5.5mm barrel connector!

Where To Buy
Setup
Getting set up with the SwitchTrick is easy. If you’re using a standard breadboard all you need to do is solder the power rails that correspond to your board, install the standoffs and you're ready to go! |
Basic use
To begin using the switch trick, select the output voltage you want to use by placing a jumper between the pins. Your input voltage must be greater than your output voltage as it is a drop-down/buck converter.
After the jumper has been connected, connect your desired power supply and turn the SwitchTrick on, you should see a green LED on the breadboard to indicate the power is on! |
Other features
If you don’t see the desired voltage for your project, you can use the ADJ to add a resistor of your choice to the SwitchTrick!
|
You can connect any voltage to the SwitchTrick through these exposed pads. |
If you wish to bypass the diodes on each power input, you can solder jumpers to these pads, but be careful! Don't connect two sources of power at once. |
