SWT is a desktop smart clock based on the STM32F103 microcontroller,
featuring an LX-12864-B5 graphic LCD.
It displays time, date, temperature, and includes a settings menu.
Warning:
The project is currently under development.
Errors and incorrect behavior may occur in both hardware and firmware.
A new schematic and PCB design are being created.However, the repository
SWT_hardware_docs
already contains:
- Full component datasheets
- Preliminary circuit drawings
- Hardware design references
At this stage, the risk of design or schematic errors is high.
A fully verified circuit and board layout will be published in future updates.
