Hello,
I forgot the 3v limits of the logic entries, and tested by error a point on a circuit with higher voltage, probably around 10v. There was a short electric noise then the xprotolab smelt bad, it doesn't power up anymore.
I just ordered a new one
but is there any chance to repear the first one ? Someone can advice on which components I should try to replace ?
thanks a lot,
David

Hi, you will need to replace at least the microcontroller, the screen and 3.3V could be damaged as well.
