Trusted Platform Module Header
The JTPM1 header is used to connect a
Trusted Platform Module (TPM), available
separately from a third-party vendor. A TPM
is a security device that allows encryption
and authentication of hard drives, disallowing
access if the TPM associated with it is not
installed in the system. See the table on the
right for pin definitions.
