Chosen Solution

I have a iPad Air 2 that keeps looping when powered on. Sometimes it show 100% battery then a few seconds later it shows the battery is drained. I know it’s the logic board. if I replace the logic board does it have to be the exact same one? Meaning if I have a 64GB LTE now do I have to get the same one for it to work. I don’t really need the LTE or the 64GB. I was thinking of getting the 32GB non LTE. Do you think this would work? Thanks in advance.

It should work you’ll just have a few extra connections for the antennas
