Shop RTC & Clock Modules by Type

Our RTC and clock module range may include products such as:

DS3231 RTC Modules: High-accuracy real-time clock modules commonly used with Arduino, ESP32, Raspberry Pi compatible boards and data logging projects.
DS1307 RTC Modules: Popular I2C real-time clock modules used for basic timekeeping, clocks, timers and microcontroller projects.
I2C Clock Modules: Clock modules that communicate using the I2C interface for simple connection to compatible microcontrollers.
Battery-Backed RTC Modules: Modules designed to keep time when the main project power is disconnected, using a suitable backup battery.
RTC Modules with EEPROM: Clock modules that may include onboard memory such as AT24C32 depending on the module design.
Precision Clock Modules: Higher-accuracy timekeeping modules for projects where stable timekeeping is important.

RTC Modules for Arduino, ESP32 & Data Logging Projects

RTC modules are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32 boards, displays, sensors, SD card modules and data logging systems. They allow a project to keep track of the current time and date, even when the main controller is restarted or temporarily powered down.

Always check the RTC chip type, communication interface, supply voltage, logic voltage, battery type, backup battery requirements, library support, module dimensions and whether the module suits your controller board before ordering.

DS3231, DS1307 & Battery-Backed Real-Time Clock Modules

DS3231 modules are widely used where better timekeeping accuracy is required. DS1307 modules are common in basic clock and scheduling projects. Many RTC modules use I2C, making them easy to connect to compatible microcontroller boards using only a small number of pins.

Frequently Asked Questions

What is an RTC module used for?
An RTC, or real-time clock module, is used to keep track of time and date in an electronics project. It is commonly used for data logging, clocks, timers, alarms and scheduled control functions.

What is the difference between DS3231 and DS1307 RTC modules?
DS3231 modules are generally used where better timekeeping accuracy is needed. DS1307 modules are commonly used for basic real-time clock projects and simple timekeeping applications.

Can RTC modules be used with Arduino and ESP32?
Yes. RTC modules such as DS3231 and DS1307 are commonly used with Arduino, ESP32, ESP8266, Raspberry Pi compatible boards and other microcontrollers, usually through the I2C interface.

Do RTC modules need a battery?
Many RTC modules use a backup battery so they can keep time when the main project power is turned off. Always check the module requirements and battery type before use.

Can you help me choose the right RTC module?
Yes. If you are unsure which RTC module suits your project, contact AuscomTech with your controller board, supply voltage, accuracy needs, battery requirements and whether you need extra memory such as EEPROM.
