Aug 5, 2024 · Introduction Seeed Studio XIAO ESP32C6 is powered by the highly-integrated ESP32-C6 SoC, built on two 32-bit RISC-V processors, with a high-performance (HP) processor with running up to 160 MHz, and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. There are different versions of the same board with slightly different pinouts. When the button is pressed, the LED turns on. Knowing which is which helps you connect sensors, lights, and other components without any guesswork. Dec 2, 2025 · Fortunately, the functionality of all GPIO pins remains consistent across all ESP32 development boards. You’ll learn how to configure GPIOs for input or output modes, read digital signals, and set pin states. Each pin can be used as a general-purpose I/O, or be connected to an internal peripheral signal. In this guide, you’ll learn how to set and read the ESP32 board’s GPIO pins as digital inputs with ESP-IDF (Espressif IoT Development Framework). Always double-check the pin location and the GPIO label before connecting any peripherals. Some are for power, some are for sending data, and others have special jobs.
