Thanks xp677. Did your board from JLCPCB work fine? I guess you purchased the Molex connectors and soldered youself. Can you comment on this process? Did you buy the connectors in your vicinity? Have you tried Alliexpress? I know you did a lot of testing on the lexus GS450H inverter communication pr...

Oh thank you so much Pacmaker. It is very clear. I am wondering whether to order the board from Damien or from JLCPCB because of much less frequent flights. I have no idea when the order from Ireland would turn up. But the order from JLCPBC could be much faster. Yet it is still risky.

Thanks PacEmaker for your comments.

1. Does Damien's board come with 2 Molex connectors? 2. Suppose it comes with the Molex connectors. Do the connectors have both male and female sides? 3. If it does not come with the connectors, we need to purchase the connectors with male and female sides, right? In that case, how difficult is it t...

Since I started this thread, Robbertjanzen has made a complete wiring diagram for the V2 board in visio. I do not know how to reference this work here so I downloaded the PDF file and upload it here.

Many thanks to Robbertjanzen for this wonderful/clean illustration.

In my previous post on running the firmware on a computer, I forgot to include the following important steps. To Verify/Compile the code under the name of " gs450h_v2.ino " (the very first version) in Arduino, we need to install Arduino Due. In doing so, go to Tools/Board:/Boards Manager i...

I have finally figured it out. 1. Download the following zip file related to Metro.h. https://github.com/thomasfredericks/Metro-Arduino-Wiring/archive/master.zip 2. Unzip the file. There were 2 sub folders. Go to the subsub folder containing " Examples folder, keywords.txt, LICENSE, Metro.cpp, ...

Thanks RE3Rotor for the instructions. I have followed the instructions but it gives me the following error. Specified folder/zip file does not contain a valid library I have tried in 2 ways. 1. From Arduino, Sketch/Indlude Library/Add .ZIP LIbrary 2. Unzipped the library, coppied and pasted it in Ar...

Now I am trying to make a sense of the code - Lexus-GS450H-Inverter-Controller/Software/gs450h_v2.ino The code has "ino" extention. So I have copied and created an Arduino file. Is it right way? The code beings with #include <Metro.h>. I have found it from https://playground.arduino.cc/Cod...

Thanks for the suggestion, xp677. I will add it.

Many thanks xp677.

With the help of slow67, I have finally got much better idea.

I still have a few questions. But I will ask them when I actually try to connect the board.

Thank you so much slow67.

Since Plug A pinouts are quite clearer to me, let's discuss on Plug B. Could anyone (slow67) answer the following questions please? 1 - 12V supply in (Is it the main power source for the brain/board? Does it work together with the ground in 20 in Plug A or the one in 20 in Plug B to close the circui...

Thank you so much for your time and clarifications.

I know that Damien and others have put so much into this and hence it is a quite robust setup. All I want to do is that to make things easy for EV converters by organising the information.

I hope that the others will contribute.

Hi all, I am a new to the forum. Thanks for the add. Having read the closely related threads, I am starting this thread purely on the connection of Damien's board, GS450H transmission, inverter and any given car. I will be asking questions a step by step. I apologize if these have been clarified som...
