Case3:Where high speed communication is of need. DS3231 RTC MODULE capable of communicating with high speed TWI interface. The DS3231 can also work on both 24Hr and 12Hr format finding applications in GPS systems. With two alarm clock and temperature sensor on board the use of DS3231 modul...
After installing the RTC library, the next part is to write the code for DS3231 and upload it to the ESP32 board. First, you have to write the code to set your current time. After you set the time in DS3231, it will remember the time and keep on running even if your ESP32 board...

Note: It’s safe to power the RTC DS1307 from a 3.3V pin of ESP32 if the current limit of ESP32 is not exceeded. But if you want to be on a safe site you can either use a separate power source for the RTC module or try the low-power DS3231 sensor whose operating range is be...
See DS3231 vs DS1307 Pinout Real-Time Clock DS1307 Module includes 12 pins. However, for normal use, it needs to use 4 pins: VCC, GND, SDA, SCL: SCL pin: is a serial clock pin for I2C interface. SDA pin: is a serial data pin for I2C interface. VCC pin: supplies power for ...
The DS1307 is a low power Full Binary (BCD) Real Time Clock (RTC) IC with 56 bytes of SVRAM that communicates through I2C Protocol.
1.2. DS3231 Pinout DS3231 works using the I2C protocol. At the heart of this RTC module, we have the accurate RTC chip designed by Maxim. This chip handles all the time functions and communicates using the I2C with ESP32 or Arduino board. ...
