Product Description

Use these 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. 

Solderless breadboard not included however this power supply fits our 400- and 830-point breadboards very nicely.

Need 5V from up to 28V? Check out the Freetronics PR28V.

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 using this cable from a PC.
