High-Precision Timekeeping for Your Next Project
Ensure your embedded systems maintain accurate time with the DS3231 AT24C32 IIC Precision RTC Module. Designed for hobbyists, engineers, and makers, this module combines the industry-standard DS3231SN real-time clock with 4KB of AT24C32 IIC EEPROM. Whether you are building a weather station, a security system, or a data logger, this compact board provides reliable timekeeping and non-volatile memory storage in a single, easy-to-integrate package.
Key Features & Highlights
- Ultra-High Precision: Features the DS3231SN chip with a built-in temperature compensation crystal, offering an accuracy of ±2 ppm (about 1 second of drift per 40 years) at 25°C.
- Integrated Memory: Includes an AT24C32 IIC EEPROM with 4Kbit (512 bytes) of storage, perfect for saving calibration data, logs, or configuration settings.
- Universal Compatibility: Fully compatible with Arduino, Raspberry Pi, ESP32, STM32, and most microcontrollers supporting I2C communication.
- Easy Integration: Pre-soldered I2C pins (SDA, SCL, VCC, GND) and a backup battery holder for seamless installation into your DIY projects.
- Low Power Consumption: Designed to operate on low voltage, ideal for battery-powered projects that require long-term timekeeping without frequent battery changes.
Technical Specifications
This module is engineered for stability and ease of use. The DS3231SN chip handles timekeeping with minimal power draw, while the AT24C32 chip provides persistent memory storage. The board features standard 2.54mm pin headers, making it easy to connect to breadboards or custom PCBs. It operates on a standard 3.3V to 5V logic level, ensuring compatibility with a wide range of development boards.
Why Choose This RTC Module?
Unlike basic RTC modules that rely on standard crystals, the DS3231SN offers temperature compensation, significantly reducing drift over time. This makes it an excellent choice for projects where long-term accuracy is critical. Combined with the onboard EEPROM, you can store essential data that persists even when the main power is disconnected, provided the backup battery is installed. It is the go-to solution for anyone looking to add reliable time and memory capabilities to their Arduino or Raspberry Pi projects.
