Modular Prototyping Holder

Modular Prototyping Board Holder.

When prototyping a new project, I switch between different sized Arduino boards quite often. While I like using a normal breadboard, sometimes keeping everything together and stable can be a pain. Just attaching a USB cable can cause these lightweight boards to twist and turn.

I thought about purchasing a breadboard / board holder, but they don't really lend themselves to quickly switching the boards out. And they don't allow for mounting some things, like the IO breakout board for the Nano. So I came up with my own design.

The base of the system allows a standard 830 point breadboard to be permanently mounted (using the sticky tape that normally comes on them), and then a modular board holder to be clamped to the board with simple toggle clamps. The board holder has a standard outside dimension, but is custom fit for each board. You can print a single base unit, and then as many different board holders as needed for each type of board that yo
