ESP32-based desktop dashboard

This is a desktop dashboard based on ESP32
. The project is available at:
https://github.com/vrxiaojie/ESP32-desktop-dashboard
and https://oshwhub.com/vrxiaojie/esp32-based-desktop-dashboard . It uses the
LCSC
ESP32S3R8N8 development board.
It can display various computer performance indicators in real time, and also features temperature and humidity detection, low-power sleep mode, automatic brightness, and OTA upgrades. The menu is based on WouoUI and is smooth and fluid.

3.2 There are currently two methods to obtain firmware for flashing
: 1.

Obtain the .bin file from the GitHub Release folder
: Clone the GitHub repository and manually configure the PlatformIO environment. 2. Compile and

flash:

Connect the development board to the computer using a Type-C cable. Use the flashing tool provided by Espressif (https://www.espressif.com.cn/zh-hans/support/download/other-tools)
. Download the firmware to the device using PlatformIO
(only for successful flashing once). Select OTA upgrade from the menu. Connect the computer to the device's Wi-Fi, open a webpage (192.168.4.1), and select the firmware downloaded from the Release folder.bin file upgrade

The 3D shell was drawn using LCSC EDA. Please open and view the open-source link with an editor.
Nylon material is recommended; it's a bit pricey, but the appearance and texture are excellent.
