## Description

The Adafruit 24LC32 I2C EEPROM Breakout provides 32 Kbit (4 KB) of reliable, non-volatile storage over a simple I2C interface. Store calibration values, MAC addresses, access tokens, or any data that needs to persist through power cycles and firmware updates — without the page-write constraints of flash memory. Built around the CAT24C32 (or equivalent) EEPROM chip, this breakout supports single-byte writes as well as faster 32-byte page writes. STEMMA QT / Qwiic connectors make wiring effortless — just plug in a compatible cable with no soldering required. Three address jumpers allow up to eight EEPROMs on the same I2C bus. Key Features 32 Kbit (4 KB) EEPROM – Organised as 4,096 words of 8 bits each I2C Interface – Up to 1 MHz clock speed; default address 0x50 Single-Byte and Page Write – Write one byte at a time or up to 32 bytes per page 1 Million Write Cycles – Durable and long-lasting storage STEMMA QT / Qwiic Connectors – Plug-and-play I2C with no soldering Chainable – 3 address jumpers allow up to 8 devices on the same bus 2-5V Power and Logic – Compatible with virtually any microcontroller or microcomputer Independent of Flash – Data persists through firmware uploads and power cycles Ideal For Storing calibration data and device configuration MAC addresses, access tokens, and unique identifiers Data logging with non-volatile persistence Projects on ARM Cortex microcontrollers without built-in EEPROM Package Contents 1× Adafruit 24LC32 I2C EEPROM Breakout Note: STEMMA QT / Qwiic cable not included. Standard header is also included for breadboard use.
