Adafruit PiRTC - PCF8523 Real Time Clock for Raspberry Pi

This battery-backed real-time clock (RTC) ensures your Raspberry Pi project maintains accurate time even during power outages. Ideal for data-logging, time-stamping, timers, and alarms, it features the reliable PCF8523 RTC chip.

The RTC integrates seamlessly with Raspberry Pi models, including Pi 1, Pi 2, Pi 3, Pi Zero, A+, B+, and Pi 4, supported natively by the Linux kernel. Its fully assembled PCB connects directly to the GPIO pins, eliminating the need for soldering.

Designed to keep time for over five years, this clock is essential for time-sensitive applications. Note that a CR1220 coin cell battery is required but not included. While the PCF8523 offers simplicity and affordability, for enhanced accuracy, consider the DS3231 precision RTC variant.
