This page is the checklist for GenBoard/VerThree with stepper driver chip


D45 options

The "D45 southern pad" (referred below) is at the board-edge, 70mm from the left side. This goes to the 12V supply pin of the stepper-driver chip.

EC36-pin25 (corner pin of EC36, closest to the PCB edge, and closest the EC18) is the 12V mains supply. The advantage of using this pin (below) instead of the "northern pad of D45" is that the stepper current is drawn directly from the EC36 supply pin, and not going through the small fuse. Therefore the small fuse can be really small (eg. 450mA) providing really effective protection.

Chose one of the 3 according to your taste:


Question ::

Q: Sombody has a picture off how this is done for better understanding?

A: D45 is on the bottom side, between ec18 and ec36 below the F1 on the top side. - DB

Question : :

Q: I have connected a vems to an Audi 1.8T car. I want to use it with ICM delete, But i have connected it to stepper ignition outputs which is in EC18plug instead of EC36 - 34,36,24,10 pins.

There is a chip called sn754410ne burned.

in these situation will it burn only sn754410ne?

If it is belongs to stepper, can i use the ecu via removing this chip, when using 34,36,24,10 pins?

Thanks.
