Development Boards
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.

Mini Development Boards




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.

Open-Source Controllers

Combine the functionality of a programmable logic controller (PLC) and the accessibility of a development board. Built around a Raspberry Pi and an Arduino-enabled microcontroller, these controllers use open-source software to make programming and troubleshooting convenient. Use them in your automated system to monitor sensors, control actuators, and support Internet-of-Things functionality, such as wireless communication with sensors and connection to cloud-computing services. Their plastic housing keeps the inner electronics protected in industrial environments. Controllers meet UL 94 V-0 standards for safety, and they’re rated IP20 to prevent fingers and other objects greater than 12.5 mm from making contact with live circuits. Mount them to DIN rails inside control cabinets.

DIN-Rail Mounts for Development Boards


Protect development boards from dust, water, and debris by mounting them to DIN rails inside control cabinets. These mounts have an open-air design to keep boards cool and prevent them from overheating. They attach perpendicularly to DIN rails, taking up less space in your setup. Use the included cable ties to secure your cords to the mount and keep connections free from strain.

Cords for Development Boards
Make quick, secure connections between your development board and your system’s components, such as sensors and actuators. These cords transmit data via I2C communication protocol, supporting up to 100 I2C devices in your system.
Machine-pin plugs and sockets use friction to make temporary connections to breadboards and the headers on development boards.
Qwiic and Grove sockets snap securely into place, making them good for short-term and long-term installations. There is no need to solder wire to your board or device.

Absolute Pressure Transmitters for Development Boards

- For Use With: Air, Argon, Nitrogen, Water
- Accuracy: ±0.25%
- Tube Connection: Unthreaded Male
- Housing Material: Stainless Steel
- Connection Material: Stainless Steel
- Temperature Range: 30° to 120° F
Measure your equipment’s pressure and send the data directly to a development board or single-board computer. Also known as transducers, these transmitters convert pressure into an electrical I2C signal and transmit it to your board by connecting a cord (not included) with a Qwiic connection. Transmitters connect directly to your machinery via tubing (not included), letting you monitor activity such as gas tank pressurization and liquid fill level.
Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature. They will only provide accurate readings within the rated pressure range.
