Project Name: ESP32 S3 | Campus Life Assistant 7
Project Author: lxy0423
DIY an alarm clock is common, but DIY a “smart alarm clock” with features like Bilibili interaction, Xiaomi bracelet interaction, and course schedule management becomes interesting.
The production cost of this smart alarm clock is around 110 yuan, based on ESP32-S3. It is a device that makes campus life more fulfilling.

Supports third-party voice assistants for Xiaomi Bracelet 4: Requires Baidu Smart Cloud’s voice recognition and UNIT’s API—KEY, anyway voice recognition can be tried for 180 days, hehe
If you want to replicate it, be sure to read the two chapters “About Components” and “About Development”.
Buy components according to the schematic. But note that AXP192 may not be available exactly the same, because the one I bought is a customized refurbished one.
If you buy a different one, the solution is not difficult, as long as the version you bought has at least one DC-DC default output of 3.3V, then slightly modify the power circuit.
Modification idea: Connect it to the 3V3 network and slightly modify the PCB. Because both of its two DCDCs are exposed, if you don’t want to redo the sample, you can carefully cut off the outputs of the two DCDCs and swap them.
DS3231 is indeed relatively expensive, I bought it about three years ago, it was six yuan for one module.If you want a cheaper RTC, I recommend a model: PCF8563. This one costs one yuan.
It is recommended to prepare two or three FPC sockets for both upper and lower connections.
DIY software ecology is always a problem.
If you develop a new App, or make some optimizations to this project and want to share with everyone… please submit a Pull Request on gitee. No matter how big or small, as long as it works and does not have the same name as other Apps, I will consider merging.If there is a conflict, I can assist in resolving it.
If you have compilation issues, circuit issues, or other problems, you can privately message the author in the original project or on Bilibili.
