Check your cable, connector and antenna to verify whether you need this adapter, or the other flavor. In specific, look for the center contact, is it an ‘innie’ or an ‘outie’? This adapter is likely best used for connecting an SMA antenna to a board with an RP-SMA connector.
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.
