Precision ground to the tightest parallel tolerance, these plates have threaded and unthreaded holes in a grid pattern to support precise positioning and repeatability when machining.

Combine the functionality of a PC with the flexibility of a development board’s digital inputs and outputs. These computers are faster than development boards and also have more memory, so they’re able to run multiple applications simultaneously. Use them to prototype or program complex automation jobs, such as controlling the movements of a robot arm or livestreaming video from a remote facility. About the size of a credit card, they easily mount inside control cabinets.

These computers run on a Linux-based operating system. To program, download an operating system onto a micro SD card (not included) and then transfer it to the single-board computer.

Use sets to start prototyping automation systems. They cannot be sold to Canada due to energy efficiency regulations. 5-piece sets come with the basic hardware needed to get the computer up and running. Use them to run local and web-based applications for your system. 94-, 96-, and 97-piece sets include all of the hardware in the 5-piece sets, as well as some electrical components. Use the components to prototype your physical system, which might incorporate temperature and pressure sensors (not included) using the Qwiic adapter, push button controls, and LED indicators.

Prototype electronics and build simple automation systems with the configurable inputs and outputs on these boards. Monitor both digital and analog devices, including proximity and temperature sensors, and control basic outputs, such as changing the speed of a servomotor or turning LEDs on and off. Their open-source software makes programming and troubleshooting convenient. Choose a board whose operating voltage can support the other devices you’re connecting to.

Boards with headers are good for making quick connections. Plug them in directly to breadboards, or connect them using jumper wires.

Boards without headers require making your own soldered connections. Use them for permanent or long-term installations.

Sets include the hardware and components needed to start building simple automation systems. Uno starter kits include an instructional project book, making them good for learning the basics of coding and electronics. Choose MKR IoT bundles for Internet of Things projects, such as linking your system of sensors to the cloud and communicating across networks.

Often used for rapid prototyping of electronic systems, these boards have various inputs and outputs to monitor sensors and control actuators. They’re smaller than other development boards, so they save space in your setup—while still having the same basic functions. Solder components directly to these boards for permanent or long-term installations. Attach headers for quick connections as you prototype. The operating voltage should support the other devices you’re configuring and connecting them to.

To program, attach a header to the board and connect the programming module (each sold separately). Connect the module to your computer using a USB cord (sold separately) and transfer your code. Once the board has been programmed, the module can be removed.

Program mini development boards and other custom circuit boards with these modules. To program your board, attach the module and connect it to your computer using a USB cord (sold separately). Then transfer the code from your computer to the development board. Once the board has been programmed, the module can be removed. Choose an operating voltage that supports the board you’re programming.

Also known as breadboards or proto-boards, these boards have 0.042” dia. holes with solder pads or strips. Made of fiberglass-reinforced plastic, they’re grade Garolite G-10/FR4 and meet UL 94 V-0 for flame retardance.

Board with solder pad allows you to make connections on one side of the board.

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

Board with solder strips creates a continuous circuit along each strip.

Board with numbered and lettered holes makes it easy to organize your connections.

Also known as solderless breadboards. A contact point inside each hole creates a connection without soldering. Use the terminal strips to connect your electronic components.

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.

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. To organize your connections, choose a board with numbered and lettered holes.

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

Drill holes of any size and etch your own circuit board design into copper-clad boards. All are grade Garolite G-10/FR4 and meet UL 94 V-0 for flame retardance. Use carbide tooling to drill holes.
