I don't think i will need the boost feature (motor has been rewound for a lower voltage) so the board that you have ordered will be sufficient for me.
If i boosted the voltage then i am sure i would end up grenading my motor from too high an RPM.
Do any of the other prototypers/beta testers need voltage boost? If not then developing the controller with 4 IGBT capability may be the way to go and save the 3 IGBT controller boards for people who don't need the voltage boost.
