The Egg-Bot Kit @ Evil Mad Scientist Laboratories…
We have mentioned Eggbot several times this year as we demonstrated it at Maker Faires in San Mateo and Detroit, as well as at the California state fair. And today, we’re very pleased to (finally) reveal the the design of our new kit.
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.

Hi
Dose any one know what stepper drivers are in the egg-board ?
I have look in the egg-board page and it’s written: Allegro A4839
But I couldn’t find any data about them at Allegro site.
Thanks Amnon
Doh- that should be A4983; I’ve sent a note and he should fix that page soon. Thanks for catching it!
Ooops. So sorry – silly dyslexia. I’ve now fixed it on the website. The driver is the Allegro A4983 chip. It’s the cheapest 16x microstepping driver I’ve found, and it is _rock_ solid. I just love the thing. Perfect for EggBot where we needed as much resolution as possible without resorting to mechanical reductions.
