The Adafruit GPIO Reference Card for Raspberry Pi Pico is a pocket-sized, full-colour pinout diagram printed on durable card stock. It provides a quick visual guide to every pin on the Pico, clearly labelling power, PWM, SPI, Serial UART, I²C, and general GPIO functions so you can wire up your projects without guessing.
The back of the card includes a quick-start guide for loading CircuitPython onto your Pico and blinking the on-board LED — everything you need to get started on a convenient 3" × 4" reference card.
Key Features
- Full-Colour Pinout Diagram – All Pico pins labelled by function for quick identification

Jargon buster
Plain-language definitions for the technical terms used above.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
