Seeeduino Crypto Board Combines Microchip ATmega4809 MCU and ECC608 Crypto Chip
With the advance of IoT, security has become critical since devices are often connected to the Internet. There are several ways to improve security and one of them is to implement hardware security via crypto chips. One of those chips is Microchip ECC608 (aka ATECC608A) secure element which we previously found in Linux based hardware such as USB Armory MK-II USB Linux computer, and the official Arduino Nano 33 IoT Board. Seeed Studio has now introduced a new Arduino compatible board with Microchip ECC608 crypto chip: Seeeduino Crypto board powered by a Microchip ATmega4809 8-bit AVR MCU.
