Muonix DS1302 Real Time Clock (RTC) Module

Muonix DS1302 Real Time Clock (RTC) Module is a compact and reliable timekeeping module designed for electronic projects and embedded systems that require accurate date and time tracking. Based on the DS1302 RTC IC, it keeps track of seconds, minutes, hours, day, date, month, and year, with leap-year compensation up to 2100.

The module uses a simple 3-wire serial interface (CLK, I/O, and CE/RST) and supports a wide operating voltage range, making it suitable for Arduino, ESP, microcontroller and automation projects. A backup battery can maintain time information when the main power supply is disconnected.
