Trusted Platform Module as a plug-in module for the Raspberry Pi. Utilizes SPI to communicate with the Pi. Compatible with all Raspberry Pi models (Pi 3, Pi 2, Pi 1, Pi Zero). Compact footprint allows for easy use of additional GPIO pins. Pins 17 to 26 are occupied by LetsTrust with a 2x5 pin configuration. A hardware TPM has a wide range of applications, including authentication, signatures, storing cryptographic keys, and more. The module can also be used as a true hardware random number generator when a good source of randomness is needed.

Features:
• Infineon Optiga SLB 9670 TPM 2.0
• Compliant with TPM Specification 2.0 Rev. 01.38
• New: Integrated support starting with Raspbian Stretch with Kernel 4.14.85 using a device tree overlay
• True random number generator
• Interface to the Pi: SPI
• Compatible with all Raspberry Pi models released so far (including Pi 3, Pi Zero, etc.)
• Compact design with a 2x5 pin header, leaving the remaining IO ports free for use
• From hardware rev 2.0 (current version) can be soldered directly to Raspberry Pi pins
• Fits in standard enclosures
• Integrated support for Windows 10 IoT.
