      Hi All,
      Connecting high power led with fixed current

      What is the best way to connect and control it with duet?
      It would be great if you can suggest if I should power externally or which pins should I use.

      Thanks a lot

        @Thierry14 those LED mustn't be connected directly to outputs of the Duet because from the specifications you provided, they don't have constant current control built in. You need to power them from a power supply that can provide 700mA constant current and be controlled from an output of the Duet.
