The RC522 is a 13.56MHz RFID module that is based on the MFRC522 controller from NXP semiconductors. The module can supports I2C, SPI and UART and normally is shipped with a RFID card and key fob. It is commonly used in attendance systems and other person/object identification applications. #RFID #Module

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 #module #STM32 #lock #OLED #reusable #module #simple-embedded #stm #sublayout

This project is a WiFi RF-ID Lock, which uses a Espressif ESP-8684 microcontroller for WiFi connectivity and a Handson Technology RC522 for RF-ID functionality. It also includes an OLED display and user control via a switch. A step-up power converter ensures consistent 3.3V power. #WiFi #MCU #ReferenceDesign #Module #ESP8684 #lock #OLED #RFID #reusable #module #simple-embedded #espressif #sublayout

This Project implements a RFID based authenticator where the RFID signal is sent to a controller and once the right authenticator Fob is sensed the controller will give the access and a display message will be given and a motor will be driven to control the locks. This circuit can be turned to operating mode and charging mode depending upon the switching.
