I wanted to use the fathom s because it was cheaper than the x. I am building my own rov atm, and I was using the s for serial communication. The reason I was asking how to wire it was bc I somehow fried my fathom s board while using it (Fried my Fathom S ROV side board. Not sure how)
And I still can not figure out how.
edit:
I figured it out! (kind of) i just tested my 12v to 5v converter, and it doesnt work. somehow the converter got fried, so the raspberry pi drew from the fathom instead. now I need to figure out why the converter broke tho.
