LCSC ESP32S3 Function Expansion Base Plate

I. Project Background
LCSC's development board department recently released the ESP32-S3-R8N8 series development boards, boasting powerful performance and exquisite craftsmanship. However, there hasn't been a dedicated expansion board for beginners and learners.
Faced with this situation, as a seasoned ESP32 developer, I felt compelled to step in and alleviate this awkward predicament.
II. Proposed
Design A functional expansion board should be designed to allow for learning ESP32 in a manner similar to learning a 51 microcontroller. This requires several essential modules found on 51 microcontroller development boards:
1. Independent buttons
2. LEDs
3. Digital tube
displays 4. Potentiometer acquisition
5. Servo drive
6. Temperature and humidity acquisition
7. OLED screen display
8. Light intensity acquisition
9. Ultrasonic radar ranging
10. 433.92MHz RF communication (advanced)
Of course, the most representative function of ESP32 is also indispensable: WiFi and Bluetooth communication.
By learning these ten+ modules, you can learn the following:
GPIO input (independent buttons)
GPIO output (LEDs)
Static display and dynamic scanning of digital tubes, analog-to-digital
conversion, timer
output, PWM
via OLED The screen driver and temperature/humidity data acquisition can learn the communication mechanisms of single-bus and dual-bus.
Ultrasonic waves can learn the output of timer PWM and pulse capture.
Serial port data transmission and reception can be learned through log printing .
The EEPROM data storage
file system can be established.
The use of ordinary Bluetooth and Bluetooth Low Energy, the establishment of Webserver intranet services, and the use of WiFi STA-AP mode can be learned.

III. Firmware Flashing and Log Debugging.
Click to jump to the online firmware flashing tool.
To greatly reduce the entry barrier for everyone, I have eliminated the flashing tool, achieving a completely browser-based online firmware flashing tool that is "no download or installation required and supports cross-systems."
Click to jump to the online serial port debugging tool
. Online firmware flashing is essential, so I have also created a completely browser-based online serial port debugging tool that is "no download or installation required and supports cross-systems."
TIPS: To switch from KEY4 to other functions, press and hold the corresponding button for 5 seconds.
IV. Physical Display (The color silkscreen printing is really beautiful).

After copying, start the following operations:
Step 1: Add Bluetooth device;
Step 2: Bind development board
; Step 3: Update interface configuration
. Done!

VII. Summary
This project has been underway for over a month, mainly due to being too busy and only being able to squeeze in fragmented time for development and debugging.
However, I believe the overall result is quite good and worth the month's effort.
My PCB design is rather amateurish, so please be gentle with your criticism.
