Product description
EEPROM memory breakout board with Qwiic connectors. Suitable for storing information separately from e.g. a microcontroller. Especially useful with microcontrollers that do not have a built-in EEPROM, such as many ARM Cortex processors.
Removes risk of accidentally overwriting the EEPROM in your microcontroller when it (the microcontroller) is reflashed. A programmable write protection for the entire memory provides additional security.
The I2C address is 0x50 but can be set with three pins to a total of eight different addresses. Two Qwiic connectors for serial connection with other memories, or completely different cards in the Qwiic system.
I/O available on Qwiic (JST-PH 4-pin) or 2.54mm connectors (headers included, not mounted).
