http://rusefi.com/wiki/index.php?title=Hardware:Stepper_motor is where all stepper-related info is currently documented (poorly)

Yes, I know, I've been there. The question is shall I be using jumper wires to the discovery board, or shall I solder the wires somewhere to Frankenstein.
Just thought of building another board on top of discovery, that would have an LCD, pads for stepper, pads for crank sensor, themperature sensor, everything that's needed. Might be not that bad idea at all? The third layer in our sandwich :-)

hello..

it is frankenstein 0.11 is the latest version?
i am planning to use a gerber at 1st page to make a copy of the board.

Yes 0.11 is the latest version.

This board is a bit forgotten but should totally work.

thanks.

if you interested i can sent you and kb1gtt few pieces of board for testing and analysis. FOC, just give me your address.
estimate fabrication around 1 month.

I have a few Frankenstein boards, thank you! These are available as kits at the store.

If on the other hand you fabricate Frankenso 0.5 - latest version - I would definitely want some samples.

need comfirmation.

gerber zip in this https://svn.code.sf.net/p/rusefi/code/trunk/hardware/frankenstein/gerber/ for frankenstein 0.11 board?

Jared, what do these M470 & M471 in the upper right corner mean?

Re: Frankenstein - cheaper ECU shield

and what's the purpose of that JP51?

does this red line in kikad mean a copper trace on the top layer?

I should have waited until I was home to read this. I don't have my normal system to check these right now and I run the risk of forgetting to fully reply.

From my poor memory, M470 & M471 are screw holes.

About JP51, I think this is typically a jumper wire, but with the option to use that pin for a different feature if so desired. I'll have to check when I get home later today.

About copper trace, how did you get that view? Is that with F11 or one of the other shading views? I believe you are correct. I think it's showing a copper trace that is placed in a copper flood.

sorry for torturing you.
I just couldn't understand what do screw holes do on the schematics..
you don't remember, which another feature was it intended initially? (such jumper could have been provisioned for pretty much every pin, it was done so just for this one).

Copper trace - I didn't want to confuse you, i used some tool to highlight it, and now looks as a shadow, but it's just the trace where the arrow is pointing. And it seems to be going from CAN pin to the screw hole for some reason (my older revision of the board is made in a different way)

Jared, one more thing. I am going to connect the output of my LM1815 board (5V signal) to the input of the third opamp, which is now something like LMV324, and then run a wire to pd6 pin. Is the not-so-rail-to-railness of this chip okay for that application, or do I need to replace it with an opamp from microchip?

At home now, still don't fully remember what JP51 is about. Perhaps we wanted the ability to move CAN to a different pin. I'm not remembering.

Screw holes on the schematic is to give you a place to screw the schematic to the wall :)

It's really a lazy thing. Drawing these holes in the edge layer is a pain. So I put them on the schematic and use the more feature rich tools for placing modules.

Those bulbs would probably work OK for at least a while. I expect 20W to draw about 1.7A. I expect the chips can drive 1A. So the chips will have a bit more heat from the MOSFET's internal resistance causing heat, but they will also have less heat as these bulbs do not have inductance energy to dissipate. So it would probably be OK. I would say give it try and keep in mind if they overheat they will shutdown. However they will probably be OK.

I'm not seeing a hole or trace like this near CONN_10X2. These were separate boards, which were them merged together. This might be a mistake in the merging process.

just wondering why wiki mentions pull-down for seemingly similar TPS and MAP 500K and 1K. Isn't 1K too much for that purpose?

Which wiki page? I would generally recommend using the Frankenso schematic. It suggests pull up and pull downs.

this one:

But if TPS and MAP output voltage, why use those? won't it affect the readings?

Interestingly, frankenso' wiki doesn't explain it, but gives a link to the above mentioned Frankenstein wiki.

You are right, that was a mistake on the wiki - fixed now. 500K-1M is the correct value, that's what I call "disconnected sensor detection" on http://rusefi.com/wiki/index.php?title=Manual:Hardware_Frankenso_board#Component_Options

Thank you for reporting yet another issue!

Hello.
I am from Iran.
I have Daewoo espero
Is this hardware works on my car?
If yes, please say which one of the circuits you have to make? What do I download link?
As the number of circuits is a lot of things I can not identify which one is new.(I know electronics and mechanics.)
Excuse my English is not good.

Where should I start?

Yes it would work

I believe http://rusefi.com/wiki/index.php?title=Manual:Hardware_Frankenstein_board has all the info you need, just read this page and all links from top to bottom. @ has recently made his own Frankenso and his own Frankenstein boards - real all his posts and maybe ask if he has unneeded boards or components he can sell you? I cannot sell to you myself.

The expectation is that you'll be hanging upside down and backwards as you are trying to reach that hard to get bolt. This text is like this such that you can read it while you work like this. :)

Is v1.2 KiCAD 5 compatible. I know they changed their part structure, so is this sketch going to have parts that point to the wrong footprints.

Also the 1st post links seams a bit old, like the .zip is all 2014, would it be better to remove all those links and just have the Git link, which seams to be the most up to date.

On the one hand SVN stuff is not broken - see how http://svn.code.sf.net/p/rusefi/code/trunk/README.md has 2019 lines, it's a nightly sync from GIT

On the other hand GIT https://github.com/rusefi/rusefi/blob/master/hardware/readme.md says "rusEfi uses KICAD 4 only. We are unhappy with how each major version of KiCAD seems to break backwords compatibility in a major way and we plan to skip KiCAD version 5 and evaluate KICAD version 6 once it's available." (let's not discuss this on this thread)

So, what problem would we like to solve exactly? :)
