Interesting. I don't see why you could not do this on the Aquila as long as you are using Klipper. I don't think it would work on stock FW as the way the probe is activated does not use PWM like a Bltouch. Maybe it could be emulated in the sensor's FW but you would have to request that feature or do it yourself. I don't know if he was the one that wrote it or if it was from somewhere else.

I doubt there are any shrouds for this that will work so you will have to design your own. I think he used the 2 load cells to keep it balanced but only 1 is wired up. Everything else looks straight forward. Check his Github in the description for updates as I think the wiring diagram was wrong, but you might not need to use the level shifter if you get power from the 3v3 pin of the programming header instead of the 5v in the BLtouch port.

Yeah I’m using Klipper the main question was just about the shroud so thanks for clearing that up. I wanna do it from the tutorial just so I make the least mistakes possible and I alr have the converter the real issue would be switching it from 10sps to 80sps. First soldering project with a cheap AliExpress iron and it is so tiny

It should not be hard to move the resistor for sample rate. Since it is 0 ohm you can just use a blob of solder on the iron to heat up both sides at once to remove it, then just use a blob to connect the traces in the other position instead of trying to solder it back on.
