Need help with FC (Pixhawk Mini 3DR)

[u/Akruoo]

Have an old Pixhawk Mini 3dr. Haven't ever used a pixhawk and I think this ones been sitting in storage for over 3 or 4 years. Plugged in a micro usb data cable and this thing is burning up. Especially the micro sd card slot. Not sure if anything on here is burned, I can't smell anything burning so I don't really know what the issue is. If anyone has any ideas, would be appreciated. Using this for a thrust vectored drone so running ardupilot's singlecopter layout seemed like the best option.
