This battery-backed real-time clock (RTC) ensures your microcontroller project accurately tracks time, even amid power loss or reprogramming. Ideal for datalogging, clock-building, timers, and alarms, it features the renowned DS1307 chip.Specifications: * Operates optimally with 5V power and compatible with 3.3V logic. * Connect seamlessly to an Arduino using our RTC library or to a Raspberry Pi. * Includes PCB and header for easy breadboard integration. * Built-in mounting holes enhance stability and convenience. * Keeps time accurately for over 5 years with a CR1220 coin cell battery (not included). The DS1307 may gain or lose up to 2 seconds daily; for high-precision needs, consider the DS3231 alternative.
