It mentions -C is ECB.

• Suffix “-C” means Center Collector (1. Emitter 2. Collector 3. Base)


Also, I pulled mine off and twisted the pins and my board is working now.

Glad you're up and running. Missed that - Guess that was a typo in the BOM. The Honey Badger uses the C versions, too.

From what I can tell, the 2.0 boards required the C version so its probably just carried over. I'm glad I was able to figure it out, hopefully there hasn't been too many people ordering off the 3.0 bom just yet.

Diodes first

Then resistors.

This end of the PCB has shorter things that the other, so I suggest this side to stuff first,

Then add your connections here. You may use the male spades, screw terminals, or bare wire, I used two types here for illustration. The Keystone screw terminals are really nice.

Relays

And finally the tall capacitors in the center.

PLEASE READ -
The current BOM asks for the -C suffix transistors, and I blindly ordered the mouser part number from it. So my transistors need to dance. Thanks bigkraig for spotting this! (Of course, i determined it after they were stuffed, so a bunch of things got un-soldered...
Hopefully the BOM can be updated with little fuss.

That's as far as I got, testing and installation to come.

Approximately how much delay is there initially before the relays turn on using the 12V power supply version? What controls this delay?

I was wondering the same thing, along with how much offset triggers the disengage mode. Are these parameters customizable?

My apologies regarding the BOM gents.
The datasheet attached to the currently specified part shows the pin outs as per the board and not as centre collector.
If somebody could confirm that Mouser 512-KSC945YTA is the correct part I will update the BOM.
Regards

Andy

Oh......
Just read the notes on the datasheet where it does indeed say the C suffix is centre collector.
My bad.
Updating BOM now.

I would be nice if their datasheet showed two pinout images showing both versions. It is quite misleading the way it is... Poorly represented and so easy to miss. I mean at least put an asterisk next to the pinout image or something.

I bought the GTA versions. I hope they will work!
