Wild thumper controller

i got a question i just wired my wild thumper controller again. cose i wanted the move the wild thumper controler board to other part of the vecle. problem is i put plus power from the battery in min and vise versa. and there came smoke out of it i imediatly removed the power but now my board seems dead or my battery got flat in few seconds. would there be a big chance i broke my board ??
