Heads up: This is the first version of this ruler. The second version is available in my Tindie store. It features more through hole components, and the Raspberry Pi Pico.

The 12" PCB ruler from Kickstarter.

A 12″ PCB ruler featuring the Raspberry PI 4 GPIO pin out, Arduino pin outs, and commonly used electronic components all on one easy to use reference! It’s a sleek ruler that’s about as unusual as they come. It’s fabricated using tough FR-4 PCB material with a green or black solder mask. The copper has a gold plated finish.
