Solderless Breadboard Power Supply 5V/3.3V

SKU 20250303

Use these neat solderless breadboard power supplies from PMD Way as an incredibly simple way to add 5V and/or 3.3V power to your solderless breadboard.

You feed it up to 12V DC through the socket (or USB power into the USB socket) with a maximum total current of 700 mA. You can then have power for both sides of the breadboard, with 3.3V or 5V on either side. 

Click here for packs of ten. Solderless breadboard not included.

Very Important Note!

The USB socket and DC socket are INPUTS and they are connected together. So if you connect 12V to the DC socket, there will be 12V at the USB socket!

You cannot power something from the USB socket - it is just another way to feed power INTO the board!
