- Current depends on power transistor, planned BD139
Does that mean, the user can decide on his own power transistor/fet (NPN) as long as you don't exceed the maximum Current suitable for the PCB-traces (or maybe even strengthen them with solder if necessary)?
Maybe a single board may be sufficent for most users. Is it possible, do design a dual board, that can be "cut" in two indipendent halves by the user?
If thats not possible i think it would be good to have dual boards (only).
Im willing to be a beta-tester for the boards (having a watercooled toolhead with oversized loud 120mm 3-wire-fans on the radiator).
I would also be interested in up to four (4) dual boards or five to six (6) single boards of the final version.
