Good idea to collect the data of the new board.
I've also considered swapping the board as my mill could do with a little more current.
I would assume that's to much.
What if its red, red silver, gold ?
0.22Ohm would set ~2.5A which seems more sensible.
What's also giving me the creaps is that the diodes on the output terminals of the TA8435 boards are the real limit.
They get already very hot with TA8435 at ~1.6A.
Hope they found soe better components or you will see them desoldering by itself ;-)
It seems to be the % of the set base current.
So based on the 0.22Ohm assumption it's based on 2.5A.
P.S. did the board finally arrive ?
