What does it do?

This is a module which includes a cryptographic chip by Infineon (an Infineon Optiga™ SLB 9670 TPM 2.0).

It has good software support – with Raspbian Kernel >= 4.14.85 there is device tree overlay support.

A TPM module like the LetsTrust TPM supports many cryptographic use cases – authentification / signatures, saving cryptographic keys, and more.

It can also be used as a True Hardware Random Number Generator (TRNG), if you need a good source of randomness.

It is compatible with all Raspberry Pis currently on the market ( Pi Zero – Pi 4). It uses the SPI interface and has a very compact design.

We have numerous customers around the world using the module in design evaluations, and some in small manufacturing batches.

For volume designs we recommend to use a custom hardware design – we are able to support you with that at affordable prices.
