I have been working on a few different shield boards for the Arduino platform. In an attempt to make life easier for myself I created a couple starter files for my future projects. The zip file below includes a schematic and PCB file in gEDA format. The board has the four headers and mounting holes for an Arduino shield board. I’ve decided to release the files into the wild for anyone to use.
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.
