Prototype your circuits with 3.3V or 5V using this breadboard and jumper wire kit! Each side rail can supply 3.3V or 5V, depending on the switch setting for that rail - this means you have the flexibility to use 5V on one rail and 3.3V on another, if this is required.
Three different sizes of M2M jumper wires are provided, to reduce clutter on circuits. The breadboard has enough space for 70 rows of holes. The power board accepts a 5V micro USB cable supply from your computer or plug pack; alternatively you can grab also use up to 12V DC power via the 2.1mm socket.
