Overview
Introduction
The ESP32-S3-DEV-KIT-NxR8 is a compact microcontroller development board with multiple interfaces.
In terms of hardware, the ESP32-S3-WROOM-1-NxR8 module is equipped with an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240MHz, 512KB SRAM (TCM) and 8MB PSRAM, and a CH343 serial port and CH334 USB HUB dual chip on board, allowing simultaneous USB and UART use and development via a USB-C interface. The pin is compatible with the ESP32-S3-DevKitC-1 development board, which is compatible with the expansion of a variety of peripherals, making it more convenient to use.
In terms of software, development environments such as ESP-IDF, Arduino, and MicroPython can be selected for development, making it easy to get started quickly and apply them to products.

The Rest of the Status Bar Introduction
- ① SDK configuration editor: many functions and configurations of ESP-IDF can be modified within it.
- ② Clean up everything and delete all compiled files.
- ③ Compile.
- ④ Current download method, default is UART.
- ⑤ Program the current firmware, please do it after compiling.

FAQ
Answer:
Check if the power supply voltage of the USB port is less than 5V. Generally, the power supply voltage of the USB port is above 4.9V, and both USB ports of the module can be used normally. If it is lower than 4.9V, there may be insufficient power supply and USB port disconnection. In this case, it is necessary to replace the USB port with sufficient voltage.
Answer:
Long press the BOOT button, then press RESET at the same time, release RESET and then release the BOOT button. At this time, the module can enter the download mode, which can solve most of the problems that cannot be downloaded.
Answer:
Our wiring sequence is different from the official Raspberry Pi rp2040. If you want VSYS, it is actually the 5V pin.
