Development of access control panel

Development of a "turnkey" device
- Creating the device concept, defining functionality and component interaction scheme
- Designing the case in SolidWorks: considering mounting of the board, connectors, control elements
- Printing parts on FDM and SLA printers
- Developing firmware for the STM32 microcontroller: implementing input processing, working with sensors, data transmission modules, display, relay, and others
- Assembling the prototype, integrating electronics, and testing the system
