All in One PCB

I’ll try it, an dI think in my case I have to plug 12V on the COM.
I’ll explore it tomorrow, and if it’s too complicated, I’ll buy the Bosch one.

Thank you to all of you :wink:

Is this the board your using?
On the standard aio pcb you only need to connect 4 wires to the relay and its all done externally. If you use the bosh NO relay and follow the guide it couldn’t be any easier and it works a treat

I use the all in one PCB, the picture I post is on a French forum.
But I think that I’ve found a wiring diagram which will fit to my case.
Schema-Monnayeur-Relais-12V

This is for a 5V relay used with the old V2 PCB.

You need a 12V NO relay, It really is simple all you need to do is crimp some female 6.3mm spade connectors.

I will make a Relay with wire tails today, picture worth a thousand words.

Mine is a 12V relay, the reference of the component on the plate is SRD-12VDC-SL.

Thank you for the future wiring :wink:

That relay is for a circuit board, it will have small pins.

You need a relay like this, you will find in your car…

They are very cheap.

Ok then I will buy this one, that will be easier :wink:



You can see an insualted female spade connecrtor with brown wire close to plug this connects to the Phidgets motor, the other wire from the motor connects to Pin 6.

Relay Pin 30: Pin 5 Ampseal
Relay Pin 85: Pin 7 Ampseal
Relay Pin 86: Pin 21 Ampseal

I now have my autosteer working but I don’t know how to enable the current turn sensor. It should be on my 2.4 version board, right? When I put it on, it only shows 1-2% and doesn’t go up even when I try to force steering wheel against motor. It just burned my fuse. Is there something I need to do to get it working?


Click on this icon and you’ll then get another bar graph pop up. Set it at roughly 30 to start with and have another play about. Remember to save after everytime you change it.
Have mine set at i think 24, any lower and it seems to trip out a bit especially when preforming headland turning

I tried that but it only shows 1-2% load on the bottom bar so nowhere near 30%. Do you need the jumper wire on the board on pressure pin or is it just for pressure sensor?

Are you using the latest firmware ino on the Teensy? There was a bug like that on an earlier version a few months back.

Try updating the Teensy.

Cant you use the arrows on the end of the box to slide the scale up to 30 ?


Also i see you have ‘switch’ selected for your steer enable, are you using a switch or momentary switch? If so i needs to be set to ‘button’ . I only ask as it caught me out once, i wss using a button but had switch selected so trying to overide the steering it was constantly try to re enable. I set to button and it cured it. Worth checking

It should have the latest version. Everything else is working fine, my screenshot was just for info on my desktop on simulation mode to show the bar.

Do I need to have jumper on red circle?

Not sure on them but don’t think so but pretty sure you’ll need some here

I have them on right and left but wondering if I need it also on remote/pressure for the current sensor to work.

Ive got the standard aio and just checked andi havnt got the jumpers where your indicating and mine works ok.
Also a screenshot of my jumpers

I just realised that I have powered my cytron directly from the pins. Does this mean that my current sensor is bypassed and that is why it doesn’t work?

Yes it probably does. Use the 24v in screw terminal to power the cytron

You need to solder the 12 or 24v pads, how is power getting to the Cytron?
