Ready-to-Use Circuit Boards

Also known as breadboards or proto-boards, these boards come with tin lead-plated copper holes and solder pads or strips, so you can solder on components. They create more permanent connections than no-solder circuit boards. Made of fiberglass-reinforced plastic, they’re grade Garolite G-10/FR4 and meet UL 94 V-0 for flame retardance.

Circuit Boards

Solder Pad Connection—Boards with solder pads allow you to make connections on one side of the board.

Solder Through-Hole Pad Connection—Boards with solder through-hole pads allow you to make connections on both sides of the board. Through-hole pads are also known as vias.

2 mm Hole Center-to-Center—Boards with 2 mm hole center-to-center spacing are also known as single Eurocards and 3U Eurocards.

Ready-to-Use Circuit Boards with Enclosure

Also known as project boxes, these circuit boards are shaped to fit the included enclosure, so you don’t have to cut your board. Made of ABS, the enclosure won’t crack or break from impact. The circuit boards have copper holes and solder pads, so you can solder components to the board for more permanent electrical connections than no-solder circuit boards.

No-Solder Ready-to-Use Circuit Boards

Also known as no-solder breadboards. A contact point inside each hole creates a connection without soldering. Use the terminal strips to connect your electronic components.

Acetal—Acetal boards handle higher temperatures than ABS boards, which makes them good for burn-in testing.

170 Total Contact Points—Boards with 170 contact points are often used for prototyping applications since they’re smaller. They’re available in a variety of colors to keep multiple prototyping projects organized.

400 Total Contact Points—Boards with 400, 830, or 2,390 contact points include distribution strips that ground connections and send power to your electronic components. Some also include connection posts, so you can connect to an external power supply.

Ready-to-Use Circuit Board Kits

Rapidly prototype and troubleshoot issues on a no-solder circuit board and then transfer your final design to a board with solder pads for permanent connections. These kits come with two boards that have the same markings and layout, so it's easy to translate your prototype to your final design.

High-Temperature Potting Boxes

These enclosures withstand temperatures up to 475° F. Made of phenolic, they resist most chemicals and are scratch resistant. However, they’re not as impact resistant as enclosures made of ABS. Use them indoors to house sensors, switches, and other electronic devices.
