## Description

The Adafruit Infineon Trust M Breakout features the OPTIGA Trust M (SLS 32AIA) secure element — a hardware crypto authentication chip that stores private keys securely, performs cryptographic operations, and generates true random numbers. It communicates over I2C via STEMMA QT / Qwiic connectors for easy solderless integration. OPTIGA Trust M is the next generation of Infineon's Trust X platform, adding RSA 1K/2K support alongside ECC NIST P256/P384. With 4.5 KB of user memory, it provides a robust hardware security foundation for IoT devices, secure boot, and certificate-based authentication. Key Features OPTIGA Trust M (SLS 32AIA) – Hardware secure element for cryptographic authentication ECC NIST P256/P384 – Elliptic curve cryptography for key agreement and digital signatures RSA 1024/2048 – RSA key generation and operations SHA-256 – Hardware-accelerated secure hashing TRNG & DRNG – True and deterministic random number generation 4.5 KB User Memory – On-chip storage for certificates, keys, and configuration data STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support Breadboard-Friendly – 0.1" header included; four 2.5 mm mounting holes Ideal For IoT device authentication and secure boot Private key storage and certificate management True random number generation for embedded security Secure communication and data integrity verification Package Contents 1× Adafruit Infineon Trust M Breakout Board 1× 0.1" Header Strip Note: STEMMA QT cable not included.
