Create an electronic calendar using the esp32s3 module

This is an original add-on meter system for automobiles. By using the ESP32, it can function as an IoT device that displays the current time, and it can also be used to create a G-sensor utilizing its built-in sensors. Of course, when combined with an OBD2 device, it can retrieve data from the vehicle and display it on the meter. Another feature of this device is that it can also be used for racing simulators, serving as an additional meter for simulation setups.

3D-printable watch case specifically adapted for the Elecrow ESP32S3 PCB with a round display, allowing you to turn this electronic board into a functional smartwatch. This project provides a practical and stylish solution to integrate the ESP32S3 into a wearable format while maintaining access to its advanced features. https://cults3d.com/zh/3 Features of the Case Ergonomic and modern design Easy and optimized 3D printing Access to the PCB's ports and sensors Robust and lightweight structure Compatible with standard watch straps With this case, you can wear a fully functional ESP32S3 on your wrist, add sensors, and create your own applications for home automation, health tracking, smart notifications, and much more. Elecrow is organizing an online competition, and I have submitted this project. If I win, I will release this case as Open Source and make it freely available to the entire community. Your support is essential. Share this project and help me give it maximum visibility
