Adafruit PCB Ruler V2.6 – 6-Inch Reference Tool With Component Package Sizes, Font Guide, Trace Width & AWG Drill Holes (Gold Plated)

About This Product

If you've ever tried to identify a tiny surface-mount component and thought "what in the world is this thing?

" – this Adafruit PCB ruler is exactly what you need.
It's about 1 inch by 6 inches, made from standard-thickness FR4 with a fancy gold plating that looks sharp and resists corrosion.
On one side you've got inch marks with 1/8th divisions, and on the other, centimeters with 0.

1cm ticks.

But the real magic is all the reference stuff printed on it.

You get common SMD package outlines – QFN, TDFN, SOIC, SOP, J-Lead, you name it – so you can visually match your mystery part.

There's also a font size guide, a trace-width diagram for PCB design, and a set of AWG-sized drill holes so you can gauge your wire thickness just by poking 'em through.

This thing is a lifesaver for hobbyists, students, or anyone who spends time at a soldering station.

Keep it on your bench and you'll reach for it constantly.
It's not just a ruler – it's a cheat sheet for all those tiny details that drive you crazy.
Adafruit nailed it with this one.
