About this item
  • A very compact real time clock (RTC) module is based on the high accuracy DS3231 IC and includes a battery backup. The (HCRASP0009) module also has a header with a pinout specifically designed so that it can be plugged directly into the IO header of your Raspberry Pi without any need for additional wires or soldering.
  • The module makes use of the Raspberry Pi's I2C hardware interface. Using our configuration guide available on our support forum it will allow your Raspberry Pi to accurately keep the current time and date without an internet connection making it great for remote data logging application where not internet connection is available.
  • Although specifically designed for the Raspberry Pi, its ability to with with both 3.3V and 5V logic levels means it can also be used with most types of microcontroller development boards such as the Arduino.
  • There is a setup guide on our support forum for this module on our support forum (Hobby Components).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
