This handy GPIO reference card is the perfect pocket-friendly go-to resource for navigating your way around the Raspberry Pi Pico.
We designed a full-color pin-out diagram and printed it on card-stock so you can parse your power from your PWM and separate your SPI from your Serial UART. All the pin uses are labeled for quick reference.
On the back, we have a quick start guide for loading CircuitPython onto your pico and blinking the onboard LED. All on a 3″ x 4″ card!
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.
