Espressif ESP32-S3
ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. Compared with ESP32, it supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.
What follows is a description of the most important features of ESP32-S3.
- Wi-Fi + Bluetooth 5 (LE) Wireless Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and BLE have superior RF performance that is maintained even at high temperatures.
- AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-WHO and ESP-Skainet.
- Rich Set of IO Peripherals: ESP32-S3 has 44 programmable GPIOs, namely 10 more GPIOs than those of ESP32. ESP32-S3 supports all the commonly-used peripherals, such as SPI, I2S, I2C, PWM, RMT, ADC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these peripherals, however, ESP32-S3 is also equipped with an ultra-low-power (ULP) core that supports multiple low-power modes in a variety of such use-cases.
- Security:ESP32-S3 provides all the necessary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption and RSA-based secure boot. In addition, ESP32-S3 has a digital signature peripheral and an HMAC module, which provide functionality that is similar to the hardware secure element, thus protecting the private or symmetric key from software attacks and identity theft. ESP32-S3 also has a “World Controller” peripheral that provides two fully-isolated execution environments, which enable the implementation of a trusted-execution environment or a privilege-separation scheme.

Software
ESP-IDF
ESP-IDF 是乐鑫官方推出的物联网开发框架，支持 Windows、Linux 和 macOS 操作系统。
建议开发者通过集成开发环境 (IDE) 安装 ESP-IDF:
- GitHub: ESP-IDF Eclipse 插件安装与使用指南
- ESP-IDF VSCode 插件 | GitHub: 安装与使用指南 | bilibili：ESP-IDF VSCode 插件快速操作指南
或者根据操作系统选择对应的手动安装流程:
API:
为了使你的BPI-Leaf-S3开发板可以通过USB-CDC刷写FLASH，需要设置开发板为固件下载模式。
有两种操作方法：
1.通过USB连接到电脑，按住BOOT键，再按一下RESET键并松开，最后松开BOOT键。
2.在断开供电的条件下按住BOOT键，再通过USB连接到电脑，最后松开BOOT键。
需要在设备管理器中确认接口，固件下载模式与普通模式下的接口序号可能是不一样的。
MicroPython
MicroPython实现了大部分Python 3 特性和语法，易学易上手，验证程序效果无需编译直接下载进芯片运行。
无论是否有编程基础，MicroPython的上手难度绝对远低于其他编程语言，其代码易读性高，且开源社区有多年积累的丰富资源，就如同Python一样拥有极强的生命力与应用价值。
Arduino
Arduino 是一个开源嵌入式软硬件开发平台，用来供用户制作可交互式的嵌入式项目。
