This is a custom smartwatch PCB I designed by myself when I was 15 for fun and educational purposes.
The goal of the project was to learn more about PCB design, low level programming, and electronics in general.
The project was done in 2023-2024. This project is the hardest thing I have ever done. Learning electronics at such a deep level was a huge challenge worth doing.
This project is experimental and not intended for commercial use.
I cannot guarantee safety, reliability, or fitness for any application — use it at your own risk.
The schematics are not guaranteed to work perfectly, after all this is my first PCB design.

- Designed in EasyEDA
- Uses ESP32-WROOM-32E-N16 for bluetooth and Wi-fi features
- A connector for a TFT LCD Touch Screen
- USB connector for programming the ESP32
- Extra memory
- A microphone for voice recordings.
- A quad-band GSM/GPRS module for SMS messages and other shenanigans
- An antenna for the module. Might not be compatible
- A Nano SIM card holder for the module
- A Litium battery managment system
- A battery connector component
- Voltage translators and regulators, see the schematic!
Note that the schematic has not been FULLY tested and it main contain mistakes, after all, analyzing datasheets in Chinese is quite hard ;)
Note: the PCB had to be ordered in such a weird form (4 PCBs) due to complications with the USB port
