that is not right, the 2561 also has its advantages, for example, ISP and UART use the same 6-pin connection

Yes, 2560 and other connectors, 2INJ, 2 IGN, 50x80mm, BT onboard, option heade for stacking ...
and now KICAD to practice with it ;)

Nice video! BTW what ignition coil do you use? Is it smart coil?
I saw thus culi before in #43617 and cannot recognize

Hi Tommy.
If you asking my opinion...
You board looks nice and elegant. But personally me install ECU directly on engine and in future want integrate it to the throttle body. So I'd rather have PCBA in "one" store, keeping most of small components at one side and few Keys at bottom.

On my subjective opinion Yes.
+ add non contact magnetic sensor instead of TPS.

Hi Tommy

This picture looks as a dream for small engine EFI. It is 2561 or 2560
Recently I observe 3 nice supercompact projects here:
Blitzbox
Kartduino H2
joey120373 project

So it is correct direction. I wish all this projects became completed and stable. I can contribute in very hard test on small engines. Can make milled throttle bodies for. I will test under vibration, frost, heat low pressure. Make thermograms, etc.

From my experience with EFI small engines the most problematic thingies are Hall sensors and TPS.
So use instead of external TPC something like AS5600 magnetic position sensor or something similar would ne very beneficiar for reliability.
