Re: NEO 29er Controller

Now... What I seek as an Engineer is to be proven wrong. What I really hope for is to find some resource where these pockets of information CAN be found and the pinouts ARE out there and we CAN upcycle all of this equipment that is about to be recycled for metal value. An entire niche industry can a...

Ah ha... clearly winning now.
I dont know who marked up that picture. . . but I think their translation is a little off.

So if we want "Winning Ducks" then apparently we have to have learnings to find
* 810 LED
* S830

Ok, onward to that goal.
