AITRIP 3PCS ESP32-S3-DevKitC-1-N16R8 ESP32-S3 ESP32 WROOM-1-N16R8 Development Boards 16M External Flash Expansion 8M PSRAM with WiFi, Bluetooth 5.0 for Arduino

ESP32-S3 product introduction:
The ESP32-S3 is an MCU chip with integrated 2.4 GHz Wi-Fi and Bluetooth 5 (LE), supporting long range mode.
The ESP32-S3 is equipped with an Xtensa 32-bit LX7 dual-core processor, with a main frequency of up to 240 MHz.
Built-in 512 KB SRAM (TCM), 45 programmable GPIO pins and extensive communication interfaces.
The ESP32-S3 supports OctalSPlflash and high capacity off-chip RAM and supports user configuration of data and instruction cache.

How to download the ESP32-53:
The ESP32-S3 downloads the burn-in program file (burn-in firmware), which can be downloaded via the ESP32's direct USB port.
Downloading can also be done via the integrated hardware USB-to-serial port.
In short, both TYPE-C USB ports on the board can be used to download programs.
In the Windows environment, you can download via the official flash_ download_ tool _xxx software. Note that the two USB port methods are once the USB method and once the UART method.
