Bit-Tree Creativity - 24Cxx Series EEPROM Module

24C08 Series EEPROM Module (A037)

BIT-TREE 24Cxx EEPROM module adopts I2C non-volatile storage, data will not be lost after power outage. It supports 2.5V-5.5V wide voltage operation, with on-board I2C pull-up resistors and power indicator. It can store parameters, serial numbers, calibration values and other data long-term, suitable for maker projects, smart car and teaching applications.

Data retention upon power loss

Easy-to-use I2C bus interface

Million-level erase/write cycles

BIT-TREE CREATIVITY

STEAM skills like programming will be a core competency for the next generation, and the time to cultivate this ability is now.
