DS1302 Real Time Clock Module RTC Breakout Board for Arduino AVR ARM (Pack of 5 pcs)

The DS1302 chip contains a real-time clock / calendar and 31-byte static RAM, which communicates with the single-chip microcomputer through a simple serial interface.
The real-time clock / calendar circuit provides information about seconds, minutes, hours, days, weeks, months and years, and the number of days per month and days in leap years can be adjusted automatically.
Clock operation can be determined by AM/PM indication in 24-hour or 12-hour format.
The communication between DS1302 and single-chip microcomputer can be carried out simply by synchronous serial mode, and only three port lines are needed: (1) RST reset, (2) I/O data line (3) SCLK serial clock.
DS1302 RTC module is widely used in telephone, fax, portable instruments, small data experiments and other product fields.
Never connect VCC and GND backwards, so as not to burn out the chip.
