The 32U4 talks USB, but is it possible (how?) to run it with a Lightning receptacle?
Use a Lightning-to-USB adaptor:
How does this help the ATMega to talk Lightning? I'd like to have a lightning receptacle ... so the ATMega has to handle Lightning isn't it?
Wait, you think about an Lightning2USB adapter between the ATmega and the receptable? Ye, dirty hack, but not really an elegant solution.
You may find this helpful, good luck!
