ACE 6629 DS3234 Real-Time Clock Module RST Input / Output for Arduino Uno

ACE 6629 DS3234 Real-Time Clock Module RST Input/Output for Arduino Uno

This is a simple breakout board for the DS3234 real-time clock (RTC) IC. The DS3234 can accurately keep track of seconds, minutes, hours, days, months, and years, so your microcontroller doesn’t have to. It even features a pair of configurable alarms. This is perfect for clocks, calendars, or any other time-keeping project. It comes with 1 CR1225 (12mm Coin Cell Battery) that will afford your RTC years-and-years of time-keeping goodness.
