The ESP32-S3-Pico is a low-cost, high-performance microcontroller development board with a compact size and rich peripheral interfaces.
Adopts ESP32-S3R2 as the main chip, which is an MCU chip with integrated 2.4 GHz Wi-Fi and Bluetooth 5 (LE).
The interface chips are CH343 and CH334, so you can experience the fun of USB and UART development with a single USB-C port, and no more trouble switching interfaces.
The DC-DC chip adopts MP28164, a high-efficiency buck-boost chip, which adopts PWM fixed-frequency current control mode to optimize circuit stability and response speed.
You can choose ESP-IDF, Arduino, MicroPython, or other development environments in software so that you can easily and quickly get started and apply it to the product.
- Adopts ESP32-S3R2 as the main chip.
- Comes with Xtensa 32-bit LX7 dual-core processor, capable of running at 240 MHz.
- Integrated 512KB SRAM, 384KB ROM, 2MB PSRAM, 16MB Flash memory.
- Type-C connector, easier to use.
- Onboard CH343 and CH334 chips can meet the needs of USB and UART development via a Type-C interface.
- Onboard DC-DC chip MP28164, high-efficiency DC-DC buck-boost chip with load current up to 2A.
- Supports multiple low-power operating states, the adjustable balance between communication distance, data rate, and power consumption to meet the power requirements of various application scenarios.
- 27 × multi-function GPIO headers.
- Castellated module allows soldering directly to carrier boards.
- Rich peripheral interfaces, including full-speed USB OTG, SPI, I2C, UART, ADC, PWM, and DVP (8-bit ~ 16-bit camera interface), LCD interfaces (8-bit ~ 16-bit parallel RGB, I8080, MOTO6800), etc. to achieve various functions flexibly.
- Note: SPI, I2C, UART, and other interfaces can be mapped to most GPIOs through the GPIO Matrix and IO MUX, see the ESP32-S3 datasheet for details.
Development Environment Configuration
- The following development system is Windows by default.
- It is recommended to develop with the VSC plug-in.
Develop with VSCode
- 1. Open the download page of the official VSCode website, and select the corresponding system and system bit to download.
- 2. After running the installation package, the rest can be installed by default, but here for the subsequent experience is recommended, it is recommended to check boxes 1, 2, and 3 here.
- After the first two items are enabled, you can open VSCode directly by right-clicking files or directories, which can improve the subsequent user experience.
- After the third item is enabled, you can select VSCode directly when you choose how to open it.
