Chapter 3: Motherboard Connections
GPIO Headers
The JGP1 (General Purpose Input/Output) header is located near the SATA connectors on
the motherboard. The JGP1 header is a general-purpose I/O expander on a pin header from
Intel SoC.
Note: The "I2C#_SCL/SDA" are pin names of Intel N3700 SoC GPIO.

TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available from
a third-party vendor. A TPM is a security device that supports encryption and authentication in
hard drives. It enables the motherboard to deny access if the TPM associated with the hard
drive is not installed in the system. See the table below for pin denitions.
