This connector supports
Trusted Platform Module
(TPM) system, which can
securely store keys, digital
certificates, passwords, and
data. A TPM system also helps
enhance network security,
protects digital identities, and
ensures platform integrity.
The header supports Serial
Link interface for onboard
SATA connections.
Please connect the thermal
sensor cable to either pin 1-2
or pin 2-3 and the other end to
the device which you wish to
monitor its temperature.
Please connect PCIE SSDs or
OCulink-to-SATA x4 cable to
the connectors.
This COM header supports a
serial port module.
