Adafruit ATECC608 Breakout Board - STEMMA QT / Qwiic

Secure your sensitive information by integrating the ATECC608 crypto-authentication chip into your projects. Unlike typical microcontrollers, this chip offers robust protection for private keys, ensuring they remain unextractable even if hardware is compromised. Simply store the key and use challenge-response queries for verification.

The ATECC608 supports ECDH and AES-128 encryption, enabling encrypting, decrypting, and signing capabilities. Enhance performance with built-in hardware for random number generation and SHA-256/HMAC hash functions, speeding up cryptographic processes for microcontrollers.

Designed for easy integration, this chip comes on a breakout PCB with SparkFun Qwiic compatible STEMMA QT connectors, eliminating the need for soldering. It operates seamlessly with both 3.3V and 5V microcontrollers and standardized I2C communication at a fixed 0x60 address, recommended for higher speeds like 400KHz.

This low-cost, secure solution fits seamlessly into existing systems and pairs with Arduino and Python/C++ libraries for straightforward implementation. While the ATECC608 lacks a dedicated datasheet, its similarity to the ATECC508 provides ample guidance for setup and usage.
