for me but I could be wrong because I am not an expert in electronic diagrams.
I have the impression that the +15V is “generated” after the smoothing by the two capacitors C3 and C24.
it would indeed be interesting if @Jhmach explained the routing of the high power on the PCB.
if I take my assembly as an example, just the 6/2 valve consumes about 36W which is about 3A on 12V on the HSP0115 alone.
the problem of recovering one of the GND pins on the Ampseal socket is that it seems to me that they are directly connected to the ground plane of the PCB, which involves cutting and bending the leg of the connector rather than soldering it.
Why would you charge your tablet through the PCB??
In my experience Panasonic tablets are happy to be powered directly by tractor power. (14.5V with alternator running)
You are missing a few headers, the 1000uF capacitors, and cny172(speed pulse output)
All of these can be added as though hole components and soldered yourself.
OK, I will try as @SjaakA suggests to connect it directly. Currently I have a converter but it heats up a lot and has even melted at the 12v in connection
I was just thinking about integrating the can bus part on the card to be able to even if my tractors are not pre-equipped and can bus.
The idea being to be able to remote and leave the section control part on the treatment devices as close as possible to the solenoid valves to limit the connections in the cabin.
Really good job from yours designing this AIO PCB…!!
I am completely new to 3d printing and I am now looking for somewhere to print these. There are some sites but does someone have recommendations where to print these in Europe?
And also what material/finishing should I use? Prices seem to jump like crazy between finishes and materials.
We are all new the first time, it is scary yes, but it is not difficult. With four tips you can do many things with a 3D printer.
I have never used printing services, when I saw the prices it was clear to me that I had to buy a 3D printer, and then YouTube is your best friend.
Give craftcloud3d.com a look. I just had them print parts for me here in the US. They are based in Germany I think. Kind of a clearing house for folks with printers.
