Pin Definition

Equipped with 29 independently configurable multiplexed GPIO pins. Each single pin can be assigned as digital GPIO, PWM output, ADC analog input, or hardware communication interface (SPI/I2C/UART). Complete pin function allocation details are available in the official pinout diagram.

Quick Start Guide

Download firmware via BOOT button operation: Hold down the BOOT button first, then plug in the USB-C cable to enter firmware download mode.

Develop via Thonny (MicroPython rapid development) or official Pico C SDK (C/C++ high-performance development).

Short press the RESET button to restart running programs.
