    This project is an RF-ID lock circuit, complete with microcontroller (MCU). It features an RC522 RFID reader for identification, controlled by an STM32F103C8T6 MCU. The structure also includes an OLED display, lock circuit, and user interface switches. Designed to operate with a AAA battery power source. #MCU #referenceDesign #simple-embedded #stm #project #STM32 #lock #OLED #template #reference-design
