so far did a pin trace and came to have this setup

just in case you're not aware, the full schematic and kicad files for the duet are available: https://github.com/Duet3D/Duet-2-Hardware/tree/master/Duet2/Duet2v1.04

thanks, let´s hope I did it right.

I ordered finally in this orientation

[apak]

well, finally got the pcb, and found that I made a mistake, but got around it.

Could program the esp from yat M997 S1, and got IP.

Do you think that I could get any trouble using this board?

@apak That's awesome, and just what I was trying to do.

Do you have an update schematic (after fixing your mistake) so I can make up a board for myself?

Many thanks

@apak if you're able to update the firmware and get an IP you should be fine.
On the LPC/STM port any issues we normally see with wiring etc prevent users getting that far, so for you to get an IP you'll be fine

[apak]

@cncmodeller sure, I will post the gerber so you can order as much as you want

That's brilliant, thanks!

@apak If you ever want to do this kind of thing again, you might want to use these surface-mount 0.1" header pins.

That way you could make the board just as big as the WiFi module instead of making it twice as big.

This is awesome project. Congratulations on getting it working.

@alankilian so I just solder those on the botton layer and the esp07s on top, nice, lest see if the footprint is available at easyEDA

[apak]

@cncmodeller https://easyupload.io/j3zvfh this is actual prototype

[CNCModeller]

@apak that's great thanks.

Will the surface mount headers idea still allow the ethernet module to fit if required?

[apak]

@cncmodeller sure, why not?

I only ask as the ethernet headers on my Duet are 1/height.

It will almost certainly generate more EMI than the on-board WiFi module, so getting CE certification for a printer using it might be difficult. Other than that, I don't see any problems. The critical traces to keep short are the ground traces and the SPI traces.

[apak]

@dc42 in that case I will try this breakboard, shorter pads

[o_lampe]

@apak
The positions of some 'vias' are pretty close to adjacent pads. The routing could use some cleaning...

[apak]

@o_lampe I have no tecnical education, I used the autoroute feature. Already ordered.

First pcb disconnects from wifi once you start to print....so DON´T use first PCB

[jay_s_uk]

@apak have you included any resistors that may be required?

[apak]

@jay_s_uk nope
