Hardware Description​

  • When using the ESP32-S3-Pico with a carrier board, ensure the ceramic antenna area remains clear; avoid covering it with PCB material, metal, or plastic components.
  • On the ESP32-S3-Pico, GPIO33 to GPIO37 pins are used for the Octal PSRAM.
  • The ESP32-S3-Pico uses GPIO21 to connect to the WS2812 RGB LED. Please refer to the WS2812 datasheet via this link.
  • When using the USB port to download firmware onto the ESP32-S3-Pico, hold down the BOOT (GPIO0) button before connecting the Type-C cable. This step is not required when using UART.

Hardware Connection​

  • When powered by an external power supply, input 3.7V to 6V power at the castellated location marked with the 5V silkscreen.

Development Methods​

The ESP32 supports multiple development methods, allowing for professional development using the Espressif official ESP-IDF framework, or rapid prototyping using platforms like the Arduino IDE or MicroPython.

The main development platforms include:

  • ESP-IDF: Espressif's official development framework, specifically built for the ESP32 series chips, providing a complete development toolchain, code libraries, and documentation. It can fully leverage all the performance and features of ESP32 and is the preferred solution for professional development and commercial products.

  • Arduino: A well-known open-source hardware/software platform offering a simple and standard C++ interface, supporting numerous microcontrollers including ESP32. Arduino has rich libraries and demos, widely used in prototyping and education, and is a popular entry-level platform for beginners. For the development environment configuration, please refer to Arduino Development page.

  • MicroPython: The simplified version of Python 3 includes core features and is optimized for microcontroller environments. It supports instant execution without repeated compilation and flashing. It provides an efficient way for developers familiar with Python to get started with ESP32 quickly. For development environment setup, please refer to the Working with MicroPython page.

  • Other Development Methods: The ESP32 development ecosystem is very rich. Besides the aforementioned platforms, development is also supported via platforms like PlatformIO, Mongoose OS, Espruino (JavaScript), ESPHome, etc., catering to the needs of developers with different technical backgrounds.
