Duet3 6HC / BerdairPump

Sorry that I ask about this topic. Don't want to scrap my board. I have a Duet3 6HC V 1.01 and would like to connect a Berdair pump. Do I need a flyback diode or is there one on the board? Gune my motor has 2 capacitors on it.

Greetings Sven

fitting a flyback Diode can't hurt imho

Duet 3 1.01 has internal flyback diodes on all OUT pins except OUT_0.
