I2C DS1307 Module Real Clock Module

Introduction: The I2C DS1307 Module is a highly accurate real-time clock (RTC) module based on the DS1307 chip. It is designed to provide reliable and precise timekeeping in embedded systems, such as microcontroller-based projects, IoT devices, and industrial applications. Product Features: * Accurate Timekeeping: The DS1307 chip ensures highly accurate timekeeping with a precision of ±2 ppm (parts per million) over a wide temperature range (-40°C to +85°C). * Battery Backup: The module includes an onboard CR2032 coin cell battery that provides power backup for the RTC in case of power outages. This ensures uninterrupted timekeeping even when the main power is disconnected. * I2C Interface: The module uses the I2C interface for communication, making it easy to integrate with various microcontrollers and single-board computers. * Compact Size: The module is compact and lightweight, measuring only 42 mm x 24 mm x 13 mm, making it suitable for use in space-constrained applications. * User-Friendly Design: The module is pin-compatible with the DS1307 chip, simplifying the integration process and reducing the need for additional circuitry. Key Usage Points: * Easy installation and integration * Durable construction for extended reliability * Multiple color options to match project aesthetics Additional Features: * Programmable Oscillator: The module allows for the frequency of the RTC oscillator to be programmed, providing flexibility in timekeeping accuracy. * Square Wave Output: The module provides a square wave output with adjustable frequency, which can be used for generating interrupts or driving external devices. * Trickle Charger: The module includes a trickle charger circuit that automatically charges the backup battery, ensuring long-term battery life.
