It communicates over I2C via STEMMA QT / Qwiic connectors for easy solderless integration.\n\nOPTIGA 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.\n\nKey Features\n\n\nOPTIGA Trust M (SLS 32AIA) – Hardware secure element for cryptographic authentication\n\nECC NIST P256/P384 – Elliptic curve cryptography for key agreement and digital signatures\n\nRSA 1024/2048 – RSA key generation and operations\n\nSHA-256 – Hardware-accelerated secure hashing\n\nTRNG & DRNG – True and deterministic random number generation\n\n4.5 KB User Memory – On-chip storage for certificates, keys, and configuration data\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support\n\nBreadboard-Friendly – 0.1\" header included; four 2.5 mm mounting holes\n\n\nIdeal For\n\nIoT device authentication and secure boot\nPrivate key storage and certificate management\nTrue random number generation for embedded security\nSecure communication and data integrity verification\n\n\nPackage Contents\n\n1× Adafruit Infineon Trust M Breakout Board\n1× 0.1\" Header Strip\n\n\n\nNote: STEMMA QT cable not included.\n\n\nResources\n\nOPTIGA Trust M Arduino Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4693,"title":"Default Title","sku":"AF-4351","price":10.11,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
