Breadboards accept most through-hole parts and up to 22 AWG wire. When you’re done or want to change your circuit, it’s easy to take your circuit apart. For best results, use solid wires when breadboarding; you’ll find [pre-cut jumper wire kits](https://core-electronics.com.au/prototyping/prototyping-wire/jumper-wire-kits.html) and [premium jumper wires](https://core-electronics.com.au/prototyping/prototyping-wire.html) especially convenient. Two sides of the breadboard have tabs and the other two sides have compatible slots, which lets you connect multiple 400-point breadboards for more prototyping space. The breadboard features a masked adhesive backing that can be used to secure it to your project. | [![](https://core-electronics.com.au/attachments/localcontent/0J10452_153183dd1b7.jpg)](https://core-electronics.com.au/attachments/localcontent/0J10452_14255fc863a.jpg) | |---| | Adhesive backing is one option for securing the Pololu 400-Point Breadboard to your project. | Also, unlike competing alternatives, this breadboard features eight mounting holes for M2 or #2 [screws](https://core-electronics.com.au/hardware/screws-nuts.html). These holes are spaced evenly down the center on a 1 cm pitch, and they provide a variety of other mounting options, such as the ability to mount the breadboard on your robot chassis with [standoffs](https://core-electronics.com.au/hardware/spacers-standoffs.html).
