i got a bit further with my problem after finding something out: JLC has severe problems with through hole parts in their assembly tool. So i started to strip down my bill of materials to only two parts and heureka, they were on their right place.
So now it's up to me finding out which part of the BOM is driving me nuts..... :?

No, the primary goal of this board was to be as small as possible. Not sure if there is a small case where it could fit in, but it is planned to draw and publish a small printable case to put it in. This will be done when the board is finished and published.

Just curious: Do you find the ao3400a mosfet to be robust enough to control fuel injectors reliably?

Time to post the first success message. We got our first engine running this week on a Blitzbox V0.0.6. Still trying to solve some problems with the onboard Lambda Controller, but the basic functions are all running fine with the lastest software release 202202 . And to answer the question of EdMcGuirk: Yes, the AO3400A are capable to drive the injectors without any problems. The engine is running semi sequential with two injectors on one channel flawlessly. So stay tuned while we try to solve the problem with the Lambda controller, hope this will be done soon...
Best regards

Excited to hear the project is still moving forward...

" The engine is running semi sequential with two injectors on one channel flawlessly. "

That's not semi-sequential


That's paired.

Unless this isn't a Speeduino ECU.
