AT24C02 I2C memory module with 256 byte EEPROM memory

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The AT24C02 memory module is a compact EEPROM memory module for microcontrollers and other electronic projects. The module uses an AT24C02 EEPROM memory chip with a capacity of 256 bytes and communicates with the microcontroller through the I2C interface.

The module has four connections for VCC, GND, SCL and SDA, making it easy to connect to Arduino, ESP8266, ESP32 and other microcontrollers with I2C support.

The EEPROM memory retains stored information even when the power supply is switched off. The module can therefore be used to store settings, calibration values, counter values, configuration data and other information that needs to remain available after a restart.

The circuit board has built in pull up resistors for I2C communication. All four connections are clearly marked on the circuit board. The compact size of approximately 1.9 x 1.1 cm makes the module suitable for smaller electronic projects.

The AT24C02 uses I2C addressing and normally has the base address 0x50 when the A0, A1 and A2 address inputs are connected to a low level. On this four pin module, these address connections are not brought out to the external connector.
