This cable is a little unusual, rather than having a USB A plug on one end, it has two Micro B USB connections! What is this for? It’s for when you have a “USB On-The-Go (OTG)” device, and you want to plug in another USB device. For example, a Pi Zero or Pi Zero W has a OTG port, as does the Arduino Zero, and anything with an ATSAMD21 that is in USB host mode. Also great for when you want to attach to a tablet or phone with an OTG port.
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.
