The DS3231 AT24C32 Real Time Clock Module adds timestamp and event scheduling information to your microcontroller projects. This module generates seconds, minutes, hours, day, date, month and year, and provides timekeeping until 2100 while compensating for leap years.

This device was added to Parallax inventory as a quick demonstration to the sample code for the Propeller 2 SPIN/PASM SPI Driver used in the Propeller 2 Live Forum and P2 Quick Byte “SPI Driver Object”. It is compatible with all Parallax microcontrollers, to provide simple visual feedback for numbers and data.

Features:

Accurate RTC manages all timekeeping functions
Battery-backup input for continuous timekeeping
Low power operation extends battery-backup run time
Breadboard-friendly 6-pin SIP header

Applications:

Create a clock project using an LCD, OLED or HDMI display
Time-stamp datalogging projects
Control events to occur at specific time of day, day of week, etc.
