Prius Gen 3 Logic Board

[DrElectrEkun]

Hello all,

I'm a VERY long time lurker but first time poster. Thanks to everyone for making such a beautiful concept a reality (open source use and reuse or existing systems). It is truly magnificent to witness.

Tl;dr: Where can I find the most recent design files, so I can draw them in kicad and submit a pull request?

I recently graduated with my PhD in electrical engineering and so finally have time to work on all the projects I've collecting, so of course my living room is now a garage. I was about to order the v1c board for the Gen 3 prius inverter (so I can parallel the power stages) on jlcpcb and noticed the -5V voltage inverter was the old version (SG3204) vs the updated LM2776 called out in the readme in Damien's github repo (https://github.com/damienmaguire/Prius-Gen3-Inverter). Upon finding that, I checked other changes called out in the build log wiki (https://openinverter.org/wiki/Toyota_Prius_Gen3_Board) (R14 in parallel with C11, for example) weren't reflected in the board or schematic pdfs. I figured I'd make the changes and submit a pull request, but then remembered that Damien draws boards in designspark (vs kicad, but the file extensions are the same/similar).

I went to download designspark and found it's only available for windows . I'm on Linux and running windows apps has been very hairy for me as of late, so I'd like to redraw the schematic in kicad and draw a new board as well (and submit a pull request). As I've been pouring over the forums, it's a bit hard to keep track of all the small improvements made, so I was wondering if there's a place where the most recent design files live (I went through Johannes' repost as well, but to no avail). Am I missing something fairly obvious to those in the know? I swear I used the search function and watched (almost) all the videos!

Thanks,
DrElectrEkun

I dunno that there's been much change in the Gen3 board in the last, oh, 5 years.

Documentation is a real challenge for the community, for a variety of reasons. We basically have an oral history, very little is ever actually written down.

Damien hasn't participated on the forums in a couple years, but there was the original Gen3 development thread which was also sort of used at the time as a community tech support thread. I don't know if Damien's updated the board since then. The couple gens of Prius hardware was one seen to have potential as the crown jewel of the cheap EV conversion, but, despite it being universally available, never really got picked up much by anyone. There's only been a handful of builds using the hardware.

I see, noted. Thank you for your reply. Brute force it is then. Looks like I have some drawing and re-lurking to do!

The good news is that there probably aren't many improvements made?
