Fried my Kiwi/BB
I unfortunately fried my Kiwisdr due to a polarity issue on the injector for the new antenna. I had the polarity reversed and did not see it until I powered it on and the kiwi (or at least the BB green) let the magic smoke out.
Now the question part, how likely is it that the kiwi board is impacted and also fried? If there is a chance that the kiwi board is still functional I would buy the BBAI-64 and give that a try.
I know the BB is fried as that won't even turn on without the kiwi board attached and powering through USB.. As the kiwi board is not available anymore I would hate that the board is fried (am still kicking myself for not checking polarity before fitting the powerpoles!)
