First, thanks for making this awesome project open source for both software and hardware!
I want an EVSE that is three phase, and can measure the current in all three phases. The plan was to remove the GFCI circuit, since I will be using an external RCD anyway. And to make two copies of the current sensing part on the PCB. (Thanks for sharing the Eagle files!)
I have been looking into the source code, and I think I can modify it to make three measurements instead of one. But I'm not sure of which analogue inputs I should use, to mess up the code and any external accessories as little as possible.
Maybe some one has did this before? I don't want to re-invent the wheel if i don't have to.
