Help ! Accidently to much voltage on kit

My mk174 kit got a voltage of 12v dc instead of 4,5v dc (turning switch on adapter :frowning:)

Now the LED is continuously on and the kit is not working anymore.

Could anyone please tell me if the ISD1600 chip has to be replaced ?

Or only one of the other components?

Most likely, only IC needs to be changed.

Thank you so much for your fast reply ! I was afraid for this answer :slight_smile:

Is it possible to purchase this chip through you? Because I can’t find it at local vendors.

Thanks again.

Only if you return the defective item to:

Velleman Projects Tech. Dept.
Legen Heirweg 33
9890 Gavere

Last question, what would be the cost involved?

Thank you !

Difficult to say, but less than the price of a new kit.
