The Secure Click Board™ carries the ATECC508 Acryptographic coprocessor with secure hardware-based key storage. The Click Board™ is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over I2C interface.
NOTE: The Click Board™ comes with stacking headers which allow you to combine it with other Click Boards™ more easily by using just one MikroBUS socket.
