EE Bookshelf: Avoid PC-Layout “Gotchas” in RF Products
RF and extremely high speed boards are some of the most difficult to layout, since there are a lot of constraints that need to be taken into account that don’t apply (as much) to regular board design. High speed boards require a concerted willingness to learn and improve, some good old detective work to figure out what happened when things do go wrong, and a willingness to put your money where your mouth is a learn by making mistakes and trying again until you understand what works and what doesn’t.
While I wouldn’t say there’s a lot of good information out there on this — there alas isn’t, and what does exist isn’t always easily accessible if you’re just getting started — Avoid PC-Layout “Gotchas’ in ISM-RF Products from Maxim does cover some of the basics of correctly layout out the RF front end on boards in a reasonably accessible manner. If you’re working on a basic RF board, but don’t know where to start with your layout, you’ll find some good tips and advice 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.
