Thanks. Not nice they charge for it though...
Can you fill me in with how you plan on using the WiFi functionality of the Photon board? What are you using on the other end to receive it? Or, are you hoping to use it to log on to a public WiFi network in the area, or a peer-to-peer network connection? Just curious.
I charge at work, where there's open wifi available, and at home, where there's my wifi available. If it just works in those two places I'm a happy camper.

Yes, although I'm not sure how much power is available from that LED signal. Plus I think having a floating ground (when the LED is off) is suboptimal. Finding a piece of metal to act as ground somewhere around (the body of the car can still be trusted to be ground on the leaf, right?) shouldn't be that hard, compared to when I thought I needed to find a 12V.
I'll test max current on the 12V and LED signals to see what I'm playing with.
