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.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
