Fried my acro naze board, did I fry my receiver also?

[Steven0000]

250 size quad.

Got a positive and negative mixed up on the two prong vbat side of my acro naze 32.
Bought a kk mini board and everything works except my orange rx620. Did I also fry it or am I doing something wrong?

I have already tried swapping the negative and signal wire and re-binding. No light on the orx has lit up since the day i fried my acro naze.

If you put power to the RX and get no lights then it's probably gone.

Good news is they are pretty cheap.
