Duet Wifi burned



  • Hello,

    I have connected the Duet Wifi board to 220 V, and the componentre 4403T 1651 375L has been broken, and I do not know where I can buy it or what I could do. In case you can help me.

    Thank you.

    That's an A4403 regulator IC, available from the usual electronic component distributors. However, if you connected VIN to 220V then I expect that other components connected to VIN have also failed, in particular the stepper driver chips, the voltage regulator input diode, and a number of capacitors.



  • That's right, we have checked and there are more components that have been burned. I do not think it's best to repair. Do you know if Duet, offers me some change or better price?

    We sometimes have refurbished boards available, you can send an email to info at Duet3D dot com to ask.

    let me get this right as im struggling to comprehend it .

    The board got damaged through user negligence and you are asking the supplier if they will bear some of the financial cost of that negligence to supply you with a replacement ? SMHIA
