Duet 3 6CH with RPi and long cable?



  • Hi guys,

    I know the documentation recommends cables no longer than 150mm for connecting the RPi to the Duet. But the mounting layout I would prefer won't allow the RPi to be mounted that close, I would need a cable around 500mm for it to work. Is there any way that would work with the ribbon cable or is any other way to connect the RPi?



  • It might work when you reduce the SPI frequency, but I think 500mm is quite a stretch for reliable operation. sometimes placement issues can be addressed by being creative, like putting the rPi "above" or "underside" the 6CH (depending on your particular electronics enclosure layout of course).
