Hello,

If you use microcontroller like attiny something else I suggest you to use a optocoupler.  ...

Hi firefan,
I see that you are using the board as a head unit. I was wondering if you are using android 4.4 as the OS. if so are you supporting bluetooth A2DP sink and HFP?  if yes, did you have to manually enable A2DP sink and HFP on firefly's android image? thanks
