Hoverboard Circuit board

[Boeta B]

Greetings,

Where can I find/buy this replacement balance censor circuit board for a hoverboard.

Slime got onto the unit and damaged some of it, and now it's malfunctioning

tried cleaning etc, but nothing..

There is practically no chance you'll get this PCB.
Your best bet is to contact the manufacturer, but for items like this they usually don't offer alternatives.

It looks like a trivial repair based on the little bit you show, damage wise, so you if you find the right person or place they will be able to repair it.
