Keep a development board and a breadboard in one handy spot for prototyping. With multiple standoffs, these holders are for use with a development board that has Arduino mounting hole patterns. They can easily hold a breadboard with 400 contact points.

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.

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.

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.
