EBB SB2209 CAN V1.0（RP2040）and BTT-SmartFilament sensor V1.0

[Cracoukas]

Has anyone succeded to connect the BTT-SmartFilament sensor V1.0 to the EBB SB2209 CAN V1.0 board ? The sensor module is not a simple switch but apparently produce a 5V supply between the signal pin and GND.

I used the formbot sensor connected to GPIO24 which works fine to detect absence of filament but I have experienced repeating print failures (printing ABS) when for some unknown reason the nozzle was blocked, I have a couple of BTT-SmartFilament sensor V1.0which would do the job to detect jammed nozzle but could not find how to connect it to the can bus.
