WOW what a cool thing!!! When are you starting to taking orders! Hahaha but the real question is how much this board can value?
They should be 15-20$
I'll check the price of the parts, but the fixed prototypes should be something like 10$.
I just tested chaining, and it seems to work.
Tomorrow, I'll test the PWM on the fan.
nice work J4bberwock. I'm keen to get my hands on a prototype.
