HSM6

Embedded hardware wallet protects hundreds of cryptographic keys

HSM6 is a legacy product. It remains documented and supported, but new designs should use a current product.

Start here

Detect physical tampering (Wiring differs per product. The shared SEN page still needs SEN 400 and SEN 500 connections.)
Lock a device for production (Binding is permanent and cannot be reversed.)
Encrypt the root filesystem (The process is the same on each of these modules.)
Encrypt sensor data on disk (The process is the same on each of these modules.)
Connect to AWS IoT
Use the hardware wallet (Wallet support is not available on Zymkey4 or HSM4.)
Free up GPIO4 (All of these use GPIO4 as the I2C handshake. The software change is identical; the wiring diagram shows Zymkey4.)
