Description

The DS3231 are low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. No need for an external crystal.

 

USE A RECHARGEABLE BUTTON BATTERY ONLY!

A regular battery will be destroyed and may blow up and cause further damage.

 

As a Li-Ion LIR2032 rechargeable battery gets closer to being fully charge, the current to it, will drop; and effectively will provide a trickle-charge to the battery.
