About this product
A compact I2C real-time clock module built around the DS1307 clock chip, with an AT24C32 32 Kbit EEPROM for data storage. It keeps time and date with leap-year compensation and uses a backup battery to keep running when the main power is off. It suits timestamps, data logging and clock projects with Arduino or ESP32.

How do I wire the DS1307 module to an Arduino or ESP32?
Connect VCC to the supply voltage recommended for your module, GND to GND, SDA to SDA and SCL to SCL. On an Arduino Uno these are A4 and A5, and on an ESP32 the default I2C pins are GPIO21 (SDA) and GPIO22 (SCL).
Does the clock keep time when the main power is off?
Yes, if a backup coin cell (CR2032 type is common) is installed in the battery holder. Without it the time resets when power is removed.
