Thanks for sharing this! I think I see an antenna port on that board, too. Interesting …

Now I’m wondering if I should take my chances and try to fix the loose micro usb port or just live with it.

Extremely helpful, thank you. But I also want to know the location of IR input which is used to learning IR commands from original remotes.
