The ribbon cable has the same connector on both ends...Zach replaced the connector on the debug board with one like he has on the RT-IHU (or maybe it was even just changing the gender). You can see the number of the big chip on the bottom, but I could not even make out the numbers on the little one with a bright light and mag goggles.
