The OKY3417 is an electronic expansion module manufactured by OKYSTAR that is based on EEPROM (electrically erasable programmable read-only memory) and features an I2C (inter-integrated circuit) interface, an AT24C256 chip and a package size of 36.5x12mm. The module offers a low-cost solution for applications requiring an EEPROM, as it comes with a 256Kb (32K x 8) memory capacity that can be re-programmed a multitude of times. Additionally, the I2C interface allows for an easy and fast connection between the module and other microcontrollers or systems. The OKY3417 is ideal for embedded systems developers and hobbyists.
