The Arduino GRANDE is one of my favorite projects I’ve made, not in small part due to the joy it seems to bring. When I demo my oversized microcontroller for people, they often break into a wide grin and shake/nod their heads, as if to say “OK, that’s ridiculous and awesome!” That was the reaction of my friend and Arduino.cc co-founder Massimo Banzi, when I showed it to him at Bay Area Maker Faire 2012. (Note: we both miss my moustache.)
I built the GRANDE to be fully functional — at its heart is an actual Arduino UNO rev 3 routed to all of the GRANDE’s pins, ports, LEDs, and reset button — and big enough to be able to teach people how an Arduino works while pointing at human scale parts. The real ones are just so danged tiny. I’ve done a few talks about the making of the Arduino GRANDE, and recently posted an Instructable about it so you may build your own. I’d truly love to see someone make a GRANDE compatible shield.
Now, as far as Adafruit goes, I’ve got my eye on embiggening one of those lovely Feather boards…
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
I’ll bet the Grande can handle some serious current! 😉
Can you provide the dimensions? I’d like to design an enclosure for it.
Ha, yes it can, Alan! An enclosure would be terrific, what sort of materials are you thinking? The "pcb" is 384.3mm x 298.9mm
