And from the side? :-) Greedy bastard I am I am.
Is the Jag a bit taller or is it an illusion?

Re: Building Jaguar A3 board Serial #1
The Jaguar case is just 3/32" taller than the MSpoo case. More photos are included in this post
That gives it just enough room to use a larger TE Connectivity automotive grade connector instead of the DB37 for those that want a different connector.
And yes, TE Connectivity (AMP) offers free samples
Different colors have different key ways so make sure you order a male and a female connector of the same color.
Look in my github.com repository in the /docs directory for the BOM to see what samples I ordered.

Awesome, might do an album after I regain consciousness tomorrow urrr later today... fail, nearly 7am, not slept. I'd like to blame you, but it was mostly my fault, and only a little bit someone else's, not really yours at all :-)

Re: Building Jaguar A3 board Serial #1
Actually the above information is WRONG, I had issues with the USB ground not being connected to the MCU ground which caused an issue with the USB comms and another issue with needing the PNP modification which was preventing the MCU from working without the USB plugged in. Since I have corrected these two issues, I have verified that the 20pF and 22pF crystal load capacitors do in fact work. The crystal manufacturer that I have chosen specifies a 20pF load capacitor for this crystal, but feel free to test other values, I have a pair of 18pF capacitors and may try those on a future build (ie: Jaguar #2) to see if they work as well.DeuceEFI wrote:I have also determined from testing various crystal load capacitors (C10 and C11) that 22pF capacitors are required for the crystal that I have specified in my BOM. I have tried 12pF, 18pF and 20pF load capacitors as suggested by another contributor but found the crystal would not oscillate using those capacitor values.

Edit the post that that quote came from to indicate that that was incorrect without removing the original content. Give it a size=50 tag if you want.

Re: Building Jaguar A3 board Serial #1
I have checked by crystal supplier that I need a 18pf Cap.
http://hk.element14.com/jsp/search/prod ... KU=1842216
I suggested the BOM may need to update as per MC9S12DP512 datasheet:
C7 OSC load capacitor
C8 OSC load capacitor
Comes from crystal manufacturer
