==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. | |||
