While Arduino boards, such as the Arduino Uno, come with built-in EEPROM for data storage, they often have limited space—typically around 512 bytes. This may not always be sufficient for applications requiring persistent storage of settings, sensor logs, or other critical data. Additionally, EEPROM has a limited write cycle lifespan, which can lead to degradation over time.\u003cbr\u003e\u003cbr\u003eThe AT24C02 EEPROM chip provides an efficient alternative, offering 2048 bits (256 bytes) of non-volatile memory. It retains data even when the power is turned off, ensuring long-term storage of important information. Communicating via the I2C interface, it is easy to integrate with microcontrollers, and standard libraries are available for immediate use, simplifying implementation. This module is ideal for projects where 512 bytes is too little, but an SD card (with gigabytes of space) is excessive. It strikes the perfect balance for storing small amounts of essential data, such as calibration parameters, user preferences, or temporary logs, making it an excellent choice for embedded systems and IoT applications.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eChip Model: AT24C02\u003c\/li\u003e\n\u003cli\u003eType: I2C EEPROM Memory Module\u003c\/li\u003e\n\u003cli\u003eStorage Capacity: 2Kbit (2048 bits) = 256 bytes\u003c\/li\u003e\n\u003cli\u003eEEPROM Interface: I2C (Inter-Integrated Circuit)\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 3.3V - 5V\u003c\/li\u003e\n\u003cli\u003eCommunication Protocol: I²C (Two-Wire Serial Interface)\u003c\/li\u003e\n\u003cli\u003eWrite Time: 5ms per byte\u003c\/li\u003e\n\u003cli\u003eData Retention: 100 years\u003c\/li\u003e\n\u003cli\u003eWrite Cycle Endurance: 1,000,000 write cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePin Definitions:\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eVCC:\u003c\/strong\u003e 3.3-5V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGND:\u003c\/strong\u003e GND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSCL:\u003c\/strong\u003e Arduino analog input 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDA:\u003c\/strong\u003e Arduino analog input 4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eImported chip, chip above the underlying code: 2ECL capacity of 2048 b (256 byte)\u003c\/li\u003e\n\u003cli\u003eOnboard chip: AT24C02\u003c\/li\u003e\n\u003cli\u003eOnboard I2C pull-up resistors are included for communication\u003c\/li\u003e\n\u003cli\u003eAll pins are leads and marked\u003c\/li\u003e\n\u003cli\u003ePCB board size: 20 mm × 11.4 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Logging\u003c\/strong\u003e - Store sensor readings and log data for IoT applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration Storage\u003c\/strong\u003e - Save user preferences, settings, and calibration data.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmbedded Systems\u003c\/strong\u003e - Retain critical data in microcontroller-based projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Key Storage\u003c\/strong\u003e - Store encryption keys and passwords securely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Automation\u003c\/strong\u003e - Maintain operational parameters for automation systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWearable Electronics\u003c\/strong\u003e - Save personalized settings for smart wearables.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobotics\u003c\/strong\u003e - Store motion profiles, PID values, and last known positions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsumer Electronics\u003c\/strong\u003e - Retain settings in smart devices and home automation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions: 25mm (Length) x 11.4mm (Width)\u003c\/li\u003e\n\u003cli\u003eWeight: 5g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x AT24C02 I2C EEPROM Memory Storage Module Data Storage\u003c\/li\u003e\n\u003cli\u003e4 x F to F Jumper wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":40708864049333,"sku":"KG218","price":39.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/AT24C02ModuleI2CIICInterfaceEEPROMMemoryModule_1.jpg?v=1778132374","url":"https:\/\/kitsguru.com\/de\/products\/at24c256-serial-eeprom-module-i2c-eeprom-data-storage-module-arduino-pic-2","provider":"KitsGuru","version":"1.0","type":"link"}
