About this item

  • DS3231 16-pin memory chips - AT24C32 ,extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
  • Highly accurate RTC completely manages all timekeeping functions.The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.
  • Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line.
  • Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus.
  • A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a μP reset.

Bought to add real time stamp to a science project. Arrived quickly. Battery included, but that’s not necessarily good news. The RTC battery holder is made for the rechargeable type coin batteries. Quick fix is to remove the tiny resistor next to the battery clip or buy the rechargeable battery instead.Took a bit to find a suitable Arduino library. Finally settled on generic RTC3231.Board has a temperature sensor which is not accurate. It’s off by 2 degrees centigrade. Though this is within the stated error margin of 3 degrees centigrade on Amazon.Bottom line — it works fine and is great value where you 2 RTC boards, 2 batteries, and a nice set of colored breadboarding wires.

DS3231 RTC clock module works without a hitch. I like that it came with a set of jumper wires for fast and easy breadboard use! CS3232 batteries not included but i used some cheap ones from harbor frieght and they work fine.

Got these for use with an Arduino Nano and various LED projects and theyre up to snuff . Will absolutely buy from this seller again.
