We have like 2000 products now. Adafruit’s not just a SpokePov, a MintyBoost, and three people like it used to be. And while there’s probably some guy named, like, Kyle who’s memorized every PID, every product name, and everything we’ve ever discontinued, we don’t expect all of you to be as awesome as Kyle is. That’s why we’re starting this – because there are products in our catalog that are still exciting, still useful, and are still things that you probably want to add to your shopping carts but just don’t know it yet. We’re calling it Journey to the Center of the Catalog – because we like Jules Verne and we like to pretend, sometimes, that Adafruit’s a giant unstoppable volcano with a bunch of really cool dinosaurs inside of it. It just so happens that today’s dinosaurs are…
“How could something so simple be so useful?”
We heard once that, in the 4th millennium B.C., some guy asked the person who invented the wheel that question. The person who invented the wheel’s answer, we were told, was something like “well it’s not actually that simple – it required engineering and innovation and this thing called mathematics that probably hasn’t been discovered yet and blah blah blah…” on and on and on until the guy got called away to go fight a minotaur or something.
Cool story, right? We mention it because stacking headers are sort of like the wheel to the Arduino civilization – meaning this thing that’s incredibly simple, incredibly useful, but still so brilliant you’re amazed they didn’t exist before the day they started existing.
What are they for? Stacking.
You put the headers on top of your Arduino and then you can add shields like our Protoshield or our Motor Shield or our Proto-Screwshield (pictured above) to get your Arduino doing all the cool things you want it to. Our set includes 1x 10-pin header, 2x 8-pin headers, 2x 6-pin headers, and one 2×3 header.
The legs are all 10.5mm long, so after PCB thickness (1.7mm) you have a height of 8.8mm – just enough to clear the Arduino’s USB-B connector. They’re also fully compatible with shields designed for Arduino R3 and the Leonardo. For shields that don’t use the 10-pin header or 2×3 header, use the 6 or 8 pin ones.
Really, the possibilities are endless. On their own, they’re just headers with longer legs just like how the wheel was just something that rolled. But then you put an axel in the center of a wheel and a board on top of it and you get a cart. And once you get a cart you start building better roads. And once you get better roads you start meeting far off civilizations. And once that starts happening – oof, sorry, we have to go fight a minotaur.
