-The [[http://​macetech.com/​store/​index.php?​main_page=product_info&​products_id=65|ChronoPi]] is an extremely accurate real time clock module designed for use with the [[https://​www.raspberrypi.org/​|Raspberry Pi]] Models 1, 2, and 3. It is based on the DS3231 temperature compensated RTC (TCXO). It includes a CR1220 battery which should last at least 3-4 years without power...longer if power is usually available. No external crystal or tuning capacitors are required.+The [[http://​macetech.com/​store/​index.php?​main_page=product_info&​products_id=65|ChronoPi]] is an extremely accurate real time clock module designed for use with all current ​[[https://​www.raspberrypi.org/​|Raspberry Pi]] models with GPIO pins. It is based on the DS3231 temperature compensated RTC (TCXO). It includes a CR1220 battery which should last at least 3-4 years without power...longer if power is usually available. No external crystal or tuning capacitors are required.
  
 The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continuously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges...the ChronoPi will drift less than a minute per year. This makes the ChronoPi very well suited for time critical applications that cannot be regularly synchronized to an external clock. The DS3231 has an internal crystal and a switched bank of tuning capacitors.
