A circuit for a gps tracker using stm32f103c8t6 and sim 808, that acquires and sends gps coordinates to a separate interfaced application. The circuit will be powered by a 12v dc battery so there a need for power regulation. there is a USB type micro B for code uploading.

This project is an RFID 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 #simpleEmbedded #stm #project #STM32 #lock #OLED #template #reference-design
