Maybe you will take advantage of my offer. If you want to assemble from pieces, the 3/5 valve is not a good solution for AGO.
why do you say that the 5/3 proportional valve is not a good solution for AOG.?
I designed and had my hydraulic diagram approved by the hydraforce technician in my sector.
the hydraforce valve in 5/3 already equips several AOG systems to my knowledge and does not pose a problem. my orbitrol is an open center type with force feedback, which was the hardest thing to solve was to regain control over the direction.
I’ll give you the schematic.

great thank you.
how is the +15V generated from the +12v in.?
do you think it can deliver a power test without overheating the PCB to power my CF-D1 tablet whose original charger delivers 15.4V?
15 V is just to indicate it is not regulated by a 12 v power source. So 15 V is the battery voltage when tractor engine is running and normally would be around 13.5 V
I believe you can also say it is a way to see there’s two different 12 v power supply.
OK, thanks,
I didn’t understand the schematic.
the 15v output can therefore be used to power my pressure sensor rather than splicing the 12V-in.
I’m going to place an order at JLCPCB, it’s a first for me.
for the pcb assembly it says to leave everything as default. there are no components on the underside.?
I leave everything as in my screenshot.?
thank you
Is there wiring diagrams?
There is some inventory shortages, what are these parts used for?
onsemi CNY172M
Monolithic Power Systems MP1584EN
PANASONIC EEEHD1E102AQ
Texas Instruments TLC081IP
Microchip Tech MCP2562-E/SN
how many of each is missing.?
optocoupler for the speedpulse output.!!
3.3V voltage regulator for the can bus chip
surface capacitor 1000µf 25v
certainly those used to smooth the current in the power input part
OP amp use in motor/valve control
micro use in communication Bus can
The 1000uF cap is the only thing missing that you need providing you are not using a Danfoss valve or canbus.
You can use the same through hole 1000uF capacitor that is used on the original V2 autosteer board.

Is there anyone from Europe who has ordered PCB’s (micro AMP) and has spare one which he is willing to sell to me? Only need one for now.
Yes that would be possible.
BUT:
We need to have a specific explanation on how to power the cytron, as I don´t understand how that should be done.
The 12V In is not enough because it passes through the D2/D6 (which I believe is for reverse power protection, and has max 3A) and then becomes the +15V line.
Maybe the +15V pin at AMPseal is also for Batt in, because the Lock mosfet HSP0115 is also powered from the +15V line?
If so, then D2/D6 is not needed.
I think if you need more amps, use the on board 24v input. Might be nice if it has a pin at the connector. Configure the solder jumpers.
Agree 
One of the 3 GND could be changed to that purpose.
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.

Don’t power your tablet through the pcb. Its is not designed with tablet charging in mind. Better to pigtail off of the input power.

I still need to use separate step up converter to get 24v to motor right?
