DS1307 Real Time Clock (RTC) Module - Without Battery
The DS1307 Tiny Real Time Clock (RTC) Module is a compact and efficient solution for maintaining accurate time in space-constrained electronics projects. Built around the reliable DS1307 RTC IC, this tiny module keeps track of seconds, minutes, hours, day, date, month, and year with automatic leap-year correction.
Using a standard I²C communication interface, the module easily connects to popular development platforms such as Arduino, Raspberry Pi, ESP32, and other microcontrollers. It operates on a 5V power supply and includes a 32.768kHz crystal oscillator for stable and precise timekeeping.
