• Compliant with TPM Specification 2.0 Rev. 01.59
• Firmware> = 15.23
• TRNG (Real Random Number Generator) – True Hardware Random Number Generator

Design & interface

• Interface to the Pi: SPI
• Compatible with all previously released Raspberry Pi models (including Pi 3, Pi Zero, etc.)
• Compact size thanks to 2×5 pin headers, so the remaining GPIO pins remain freely available
• Can be firmly soldered with Raspberry Pi pins
• fits into common standard housings

Software support

• from Raspbian Stretch with the kernel 4.14.85 build in support with a device tree overlay
• Built-In Support for Windows 10 IoT (on Pi 2, 3, 3B +)

Software downloads

• TPM2 software
• ELTT2 Infineon Embedded Linux TPM Toolbox 2 for TPM 2.0 – test, diagnostics, etc. for the Infineon TPM chip
• Script examples for getting started & installing the TPM 2.0 tools

Scope of delivery:

• LetsTrust TPM module
• 8-pin header (installation aid to determine the correct position for the TPM module without counting)

particularities

• The LetsTrust TPM board is developed in Germany
• The PCB production of LetsTrust TPM takes place exclusively at a Bavarian assembly company
• The TPM can optionally be permanently soldered

Hardware installation:

Step 1: Attach the 8-pin header to pin 1 of the Raspberry Pi

Note: the picture shows the Pi Zero WH (with pre-soldered header). The LetsTrust TPM is of course also compatible with the Raspberry Pi 1/2/3.
The pin header has pins at the top that can be used directly for other projects if necessary. Attaching the 8-pin header is used to determine the correct pins for attaching the LetsTrust TPM module and is not required for its function.

Step 2: Plugging in the LetsTrust TPM module
The module is plugged directly next to the 8-pin header.

Hints:

• Pi Zero WH not included, but recommended for easy plug & play entry without soldering
• Software installation necessary to use the module – see www.letsTrust.de from Rasbian with Kernel 4.14.85 DTO support.
• The module also works under Windows 10 IoT Core and the platforms Pi 2, 3, 3B + supported by it!
• The module is delivered with firmware> = 7.85
