- Serial I/O ports use a minimum number of pins DS1302 Clock Module - Real-Time Clock Module for Arduino with LCD Display - GND - Ground This DS1302 real-time clock module is designed with a single PCB panel and measures 44mm x 23mm x 1.6mm. It includes backup battery with genuine celestial CR2032, voltage of 3V and 260mAh current. The module operating voltage is compatible with both 3.3V and 5V microcontrollers, and has a working temperature range of 0 to 70 degrees Celsius. - Dual power tubes used for the main power supply and backup power supply - Optional industrial temperature range of -40 to +85 This clock module is perfect for use with Raspberry - DAT - P01 - Simple 3-wire interface - Read/write clock or RAM data transfer with byte or multi-byte transfer mode transmission character set - Real-time clock/calendar with energy calculations up to 2100 - Vcc = 5V and TTL compatible DS1302 Key Performance Indicators: - 2.0V operating current of less than 300nA - RST - P00 Please remember not to reverse the polarity of VCC or GND as it can damage the chip. Additionally, a pull-up resistor is required for the C51 MCU P0 port. If your device does not have a pull-up resistor, you can connect to other ports data lines. The DS1302 I2C RTC Real-Time Clock Module is a high-quality clock chip that includes a real-time clock/calendar and 31 bytes of static RAM. It communicates with the microcontroller via a simple serial interface, providing information on seconds, minutes, hours, days, weeks, months, years, and even leap years. The clock operation can be set for either 24 or 12 hour format. The DS1302 only requires three lines of communication with the microcontroller: RST Reset, I/O data lines, and SCLK Serial Clock. This clock module is designed for low power consumption, even maintaining data and clock information with less than 1 mW of power. Wiring methods for connecting the DS1302 clock module to a microcontroller are simple with only five steps: - CLK - P02 - Wide operating voltage range of 2.0-5.5V - VCC - +5V/3.3V
