our PrettyPins project lets us create beautiful and, more importantly, *correct* pinout diagrams by drawing exactly what is connected to the EagleCad/Fritzing pins and defined in circuitpython or arduino. https://github.com/adafruit/PrettyPins
by cross-referencing all the names and io pins with a csv table of capabilities we can know for sure what the pinmux is for each pad. we do have to create that csv table first, tho! here we are, slowly going thru the ESP32 datasheet to tablify all the gpio capabilities – this is the only part that needs to be carefully done since an error here will propagate to all pinout diagrams. its slow going but at least we only have to do it once per chip!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
