Chapter 3: Motherboard Connections
32-Pin Connector A (JF1 + JGP1 + J6)
The A2SAP-H combines JF1, JGP1 and J6 into a 32-pin, 2.0mm pitch pin header, including the
front panel (power/HDD LED, power/reset button), 8-bit GPIO, and two USB 2.0 connections.
Refer to the table below for pin definitions and the female mating connector information.
The distance between the board-to-board stack is 11mm in height while using the male pin
header (PINREX P/N:225-97-16GBEW) to stack onto the female mating connector (PINREX
P/N: 620-92-16GB00).
