I don’t do a lot of PCB design, just the occasional hobbyist odd and end… but I DO know computers, freeware, etc… I’ve used Eagle (some), but really like what I’ve seen of KiCad so far, and would commend it. Another interesting option is DesignSpark.I’ve published a comparative review of PCB CAD software for hobbyists… Goes into pros / cons of Eagle, KiCad, DesignSpark, plus less extensive comments on some other options.
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.
