HATL02FPC Raspberry Pi - fan control & cryptography module, I2C

Automatic fan control module for Raspberry Pi with 5-V port on the top, including cryptography module and I2C interface.

Compared to the RPI CRYPT FC, this module externally routes I2C/TxD/RxD pins via a second connector.

Keep your software safe from theft with this MaticControl crypto module.

Most microcontrollers are not designed to protect against snoopers, but with a crypto authentication chip you can safely lock away private keys. Once the private key is stored in the chip, it can no longer be read out, it can only receive challenge-response queries. This means that even if someone gets your hardware in their hands and can read back the firmware, they won't be able to extract it!
