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…
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
