2017 REVIEW

Arduino ZS-042 RTC (Real Time Clock) Module

DS3231 RTC Module

2017 OCTOBER | by Gene Casanova

Senior Systems Engineer


ZS-042 Real Time Clock Module (RTC)

This is a Real Time Clock (RTC) IC DS3231, a battery charger, battery holder, address configuration jumper solder pads, and TTL level output pins.

A real time clock IC mounted to a small printed circuit board (PCB), with a voltage regulator IC chip and a button battery holder.

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.

The module uses the I2C Communication Protocol to communicate with an Arduino systemboard.

DS3231 IC

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.


Disable Onboard Battery Charger

Desolder and remove the resistor 201 (200 ohm).  After removing the resistor, a high grade CR2032 button battery can be used in the battery holder without a charge current going through it.

RC2023 Button Battery

A quality grade CR2032 button battery, can last in this RTC for 10 years!  The CR2032 button battery is a very commonly used battery in many consumer electroncis and X86 desktop, tower, and server computer motherboards. 


Arduino & ZS-041 Connections

VCCArduino 5V
GNDArduino GND
SCLSCL or A5
SDASDA or A4

The Arduino UNO and MEGA systembaords, provide dedicated 'SCL' and 'SDA' pins.   Full functionality is available through the I2C interface, now enabled by the two pin connections 'SCL' and 'SDA'.


Arduino Programming Language Library

There are many Arduino source code libraries available on the Internet for programming the DS3231 IC time and calendar.


ZS-041 Module Pinouts

VCC
Connect the 5V or 3.3V from your Arduino or circuit here to power the module
GND
Ground connection; -VDC; Connect this to an Arduino systemboard GND pin.
SDA
This is the I2C bus data pin.  Connect to an Arduino UNO 'SDA' pin; Older Ardunio systemboards, use Analog I/O pin A4.
SCL
This is the I2C bus clock pin.  Connect to an Arduino UNO 'SCL' pin; older Arduino systemboard, use Analog I/O pin A5.
32K
The module provides a 32kHz square-wave output at this pin.
BAT
Battery connection + VDC Input; Backup Time Power Provided By This Battery.
SQI
From this pin comes the controllable square-wave.
RST
IC Reset.
