All info on this page was found through Google's excellent Chromium wiki or inferred through documents provided by that wiki. If you try to open your peach-pi you will void your warranty, break your device, burn down your house and smell like fish for a period of no less than one month.

The debug connector on peach-pi provides various signals broken out from the Exynos5800 AP, the STMxxx EC, as well as stuff like JTAG and portions of the keyboard matrix. It is a valuable resource for debugging low level problems on peach-pi, remotely working with the unit, automating tests and generally being a cool hacker.

If smelling like fish is no problem then continue on.
