Hallo, I'm approaching the end of my Hammond MIDI controller building (here a lot of post with a lot of pictures)
I'm using a Brain V1
I would like to have a led on my controller that lights up when the Brain is connected and the host is enabled.
Is there a pin where I can "bring out" such a signal? a sort of "replica" of the built-in led soldered directly on the brain surface
I was reading the wiki about the External Header JP3 and the pin #9 (RG3/!SHDN) or #13(VDD) or #14(VCC) but I'm not sure it's safe to use it and I don't know which one to choose.
