Extended I/O Header
The extended I/O header at JEIO_1 on the A4SAP-H motherboard provides flexibility support for the following functions: DP/HDMI, one PCIe 3.0 x1, two USB 2.0, eSPI, SATA, SMBus, and Power, so that it allows you to make your own I/O module to fit different kinds of vertical market I/O demands.
For a detailed diagram of the A4SAP-H motherboard, see the layout under Motherboard Quick Reference.
