The CircuitPython Essentials guide has a new page: CircuitPython Pins and Modules! Learn about how CircuitPython knows where to look for the hardware you have connected to your microcontroller board.
This guide page explains import board and how to use board to find all the available pins and board-specific objects available to you for your microcontroller board. It also explains what built-in modules are in CircuitPython, and how to find out which ones are available for your specific microcontroller. You’ll find this page in all of the microcontroller guides, as well as part of the Essentials guide.
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.
