Revision note: As of Friday, August 28th, 2015 these now have unique MAC addresses! That’s great because now you don’t have to worry about using two or more of them at once, handy for people turning these into beacons.
Add Bluetooth capability to your computer super fast with a USB BT 4.0 adapter. This adapter is backwards compatible with v2.1 and earlier, but also supports the latest v4.0/Bluetooth Low Energy. Inside lies a CSR8510 Bluetooth USB host.
We’ve used this with great success on a Windows 7 computer, installing as a ‘generic’ Bluetooth device, but we expect it to work just fine with any modern computer as this chipset is very common. So far we’ve tested it to communicate with Bluetooth data modules only.
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.
