Ready-to-Use Circuit Boards

Ready-to-Use Circuit Boards

Also known as breadboards or proto-boards, these boards have 0.042” dia. holes with solder pads.

Circuit Boards

Circuit Boards

Drill holes of any size and etch your own circuit board design into copper-clad boards.

Solderless Ready-to-Use Circuit Boards

Solderless Ready-to-Use Circuit Boards

Also known as solderless breadboards. A contact point inside each hole creates a connection without soldering.

Development Boards

Prototype electronics and build simple automation systems with the configurable inputs and outputs on these boards.

Single-Board Computers

Combine the functionality of a PC with the flexibility of a development board’s digital inputs and outputs.

Holders for Development Boards

Keep a development board and a breadboard in one handy spot for prototyping.

Programming Modules for Development Boards

Program mini development boards and other custom circuit boards with these modules.

Mini Development Boards

These boards are smaller than other development boards, so they save space in your setup—while still having the configurable inputs and outputs that make them good for rapid prototyping.

Circuit Board Headers

Use these headers to make quick, temporary connections to development boards and other circuit boards when prototyping.

Open-Source Controllers

Open-Source Controllers

Combine the functionality of a 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.

Circuit Board Battery Holders

Circuit Board Battery Holders

Enclosed Battery Holders

Holders have snap-on or screw-on covers to fully enclose and protect batteries.

Circuit Board Battery Contacts
