proper HW

[gkasprow]

I designed proper HW for emulator https://github.com/gkasprow/battery_emulator/wiki I'm waiting for comments from you, and I can add some features needed for other batteries. I need it for LEAF batteries. The schematics are here https://github.com/gkasprow/battery_emulator/files/15213206/Battery_emulator.PDF

Nice work @gkasprow !

We are actually trying to move away from the LilyGo boards completely, due to the need for 2x CAN buses, and CAN-FD. This new board design that one Discord member is working on has built in relays for precharge and contactor control:

But having more alternatives is always better! Feel free to make a separate Wiki page about your add-on board!

[gkasprow]

I like it! Do you have schematics? I'd like merge these two projects into one.

[gkasprow]

We are working on open hardware projects for years. Example is https://sinara-hw.github.io/. It consits of nearly 90 sub-projects. We have the sponsor for the boards. So I can produce let's say 10 pcs and give them away to the active community members for intensive tests.

More peeps on the hardware can be no bad thing. Thanks Greg.

[gkasprow]

Yes, but it's better to support and maintain a single HW version at least from a software point of view. That's why I need schematics to make my HW compatible with the SW you are developing.

be careful, the circuit diagramm has changed: https://private-user-images.githubusercontent.com/81711263/328879150-d68caf7d-a0c3-4602-89bd-a701bb759d9a.png?jwt=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.WIRpOhdJhME19GrJQ9YwGUeL4yIluKHOCX64Y0kfWkQ

I added second CAN and fixed the updated schematic ; if there is interest I can also integrate Lilygo board into my board as a single design. For the moment I ordered PCBs because I have the Lilygo boards and will use them.

@dalathegreat I see refrences in many places to Discord but don't see anywhere a link to join. Tried searching in Discord's "Discover" section but not found.

btw I managed to make my HW workin with Leaf battery. I will make new revision with all the issues fixed. The major issue is that you cannot talk too early to BMS because it gets locked. I had to delay ESP32 reset.
