I'm ready to get a PCB made.

Everything is on this Github

Not dead yet! Due to various excuses that I won't belabour you all with, I haven't had the most time to work on the inverter. However, I am moving forward slowly.

Right now, I'm in the process of using a Huebner board to spin a small motor I have in manual mode using the method Damien used in his older video (lobotomise board, put the main cap back on, etc.), and I thought I would post how I plan to do that before I cover everything up.
100 ohm resistors removed for both MG1 and MG2 enable lines.

820 ohm resistors removed for all 6 gate drives.

The reason I removed the resistors was to not interfere with the OE circuit (break anything). I'll post a video once I have something up and running!

I look forward to seeing how it goes.

I have received my PCBs and was going to test it out this week but another job may have pushed that back.

What's the status on this? I'm considering using my GS450H inverter with johannes brain, do you think I wouldn't be too far off if I'd base my board on your latest pinouts?

I haven't tested the PCB yet - too many projects :D

The thing with the Camry Inverter is that not all the Fault and Temp lines have been identified. This is not a problem for my application.

If you use my gerbers it will cost $10 or so at JLC to try it out :D

The physical dimensions, holes and connector positions are fine.

do you have any news on this project?
right now I'm disassembling the gs450h inverter for the purpose of foaming the native board onto the v3 Johu board and making the output of both igbt parallel to one motor to increase power.
