Design with W23Q128FV serial Flash Memory in Cirkit DesignerThe W23Q128FV is a high-performance serial Flash memory device with a storage capacity of 128 megabits (16 megabytes). It utilizes a Serial Peripheral Interface (SPI) for fast and efficient data transfer. This component is widely used in applications such as embedded systems, consumer electronics, and automotive devices for reliable data storage and retrieval. Its compact design and robust performance make it an ideal choice for systems requiring non-volatile memory.
This circuit connects an FTDI USB-to-serial converter to a standard serial interface via a J26 connector. It facilitates serial communication by linking the ground, transmit, receive, data terminal ready, and request to send signals between the FTDI chip and the J26 connector.

This circuit features an STM32F103C8T6 microcontroller interfaced with a membrane matrix keypad for input, an RTC DS3231 for real-time clock functionality, and a 16x2 I2C LCD for display. It controls four 12V geared motors through two MD20 CYTRON motor drivers, with the motor power supplied by a 12V battery regulated by a buck converter. The battery is charged via a solar panel connected through a solar charge controller, ensuring a renewable energy source for the system.

This circuit is designed for access control with time tracking capabilities. It features an NFC/RFID reader for authentication, an RTC module (DS3231) for real-time clock functionality, and an OLED display for user interaction. A 12V relay controls a magnetic lock, which is activated upon successful NFC/RFID authentication, and a button switch is likely used for manual operation or input. The T8_S3 microcontroller serves as the central processing unit, interfacing with the NFC/RFID reader, RTC, OLED, and relay to manage the access control logic.
