You will at the very least replace all polarised capacitors and the main voltage stepdown IC. If the negative voltage reached the CPU, the whole SBC is dead. If so buy a new reputable SBC with a decent sized community. You will find little support here.Good luck.

Thank you for reply. I think buying new one is better.
