So I new in the forum, but I´ve been doing some resource around the TL-MR3040 as you can see in the Wiki.
So far I could confirm 7 free GPIOs, 6 near LED4 and the other near flash memory, wich for now, I could only control 3 of them as described in the next photo.
I'm now writing this, because, I can´t really be sure of my research because I don´t have the right equipment/stuff to test the router and make sure that these are really free GPIOs and if we can use it.
This is why I asking for help from those who have an MR3040 or MR11U to confirm this GPIOs, but all the help is welcome.
Once again I wanna say thanks to Jarocks and his Reverse Engineering the TL-MR3040 for providing good photos for the research
EDIT: Updated Photo with free GPIOs
