While we really suggest buying the NFC Breakout for use with libnfc (it was literally designed with this goal in mind!), Jerome Bernard posted up some details on getting the NFC shield working with libnfc on a Mac. Thanks Jerome for taking the time to share the details with other shield users. Have a look here!
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.
