So as for a board, what is the cost for the parts etc to make a board?
If I paid for the board/ boards up front, would you make them and ship them?

Just built one driver board today. Went together very well. What values should be used for Cs and Ctrip?

The default desaturation detection time is 3uS, so if you are switching fast, the datasheet suggests just to leave out Ctrip. They only recommend it if you are using large gate resistors to slow the switching way down.
Cs allows for a softer shut down when there's a desaturation detection. The default soft turnoff time with no Cs is about 9uS. If that's not slow enough, Cs = 100pF has turnoff time of 13uS, all the way to Cs = 800pF giving a turnoff time of 47uS.

For CM400DU-12F modules, no capacitors are needed in Cs and Ctrip.

Hi Adam
What progress on the prototypes?
Any idea how long before we will be able to buy kits??

Hello Guys,
Sorry, the controller is not ready yet. I have not had time to work on this in the last few weeks. Im on vacation for the next month so I don't expect to be working on it then as well.
Sorry for the inconvenience.
Without a123 batteries easily available for my Corvette build anymore, I have lost my motivation to get everything done as there is not really any high performance batteries out there currently.
-Adam
