‘Antenna Design and RF Layout Guidelines’ White Paper from @CypressSemi #radio
This is an absolutely exhaustive document from our friends at Cypress Semiconductor on antenna designs and RF layouts, specifically looking at implementations using their PRoC BLE and PSoC 4 BLE 2.4-GHz radios, with supporting Smith charts, and examinations of band emissions, network topologies, and much, much more. If you have a long train ride in your near future or are looking for a good antenna/RF read, take a look at this white paper.
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.
