Adafruit Infineon Trust M Breakout

This STEMMA QT breakout board carries the Infineon OPTIGA TRUST M SLS 32AIA security chip for developers adding hardware-based cryptography to embedded projects. It provides an I2C interface and includes a 0.1 inch header for breadboard or perfboard use.

4.5K user memory with RSA and ECC

The chip offers 4.5K of user memory alongside RSA 1024/2048 and ECC NIST P256/P384 support, plus SHA-256, TRNG and DRNG functions. It handles secure key storage and true random number generation but lacks the larger memory or different algorithm sets found in other secure elements.

Low-power cryptographic operation

The board draws minimal current during cryptographic operations and runs silently with no active cooling required. Its 1.8 gram weight and 4.7 millimetre profile add negligible thermal load to a prototype, making it suitable for compact, battery-powered designs.

Questions about this item

Will this Infineon OPTIGA Trust M breakout work with my existing 5 V I2C devices?

The board uses STEMMA QT connectors for I2C and includes level shifting, so it can operate alongside 5 V logic devices on the same bus.

How can I verify the Infineon OPTIGA Trust M SLS 32AIA is functioning after wiring it up?

Run the Infineon Arduino library example sketches; successful RSA 1024/2048 or ECC P256/P384 operations and true random number output confirm the chip is working.

What ships with the board and what must I provide separately?

One breakout board with 0.1 inch header pins and four 2.5 mm mounting holes are included; a STEMMA QT cable is not included.
