Adafruit Precise DS3231 Real Time Clock (PiRTC) for Raspberry Pi is a battery-backed real-time clock that keeps track of time when the power is lost. This real-time clock is suitable for data-logging, clock-building, NTP servers, time-stamping, timers, and alarms. The PiRTC is equipped with the Maxim DS3231 temperature-compensated real-time clock with an internal MEMS resonator. This real-time clock is suitable to operate with the Raspberry Pi 1, Pi 2, Pi 3, Pi 4, Pi Zero, A+, or B+.
