When plugged into a computer’s USB port, phatIO (pronounced “fat-eye-oh”) appears as a USB filesystem/memory stick. You can control devices connected to phatIO by writing to files on that filesystem. Any computer that can write to a USB memory stick and any program/language that can write to a file can talk to phatIO and control things.
phatIO significantly reduces the effort needed to control things with a computer – no drivers have to be installed or low level libraries used. Each of the 20 general purpose IO pins can be controlled by saving a “0” or “1” to their control file.
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.
