Hi! I am working on a small wirelessly powered project and am having considerable trouble with finding a qi coil that is small enough and also has a charging circuit. Specs:
1" square at most
5v at 500ma
ferrite shield
charging circuit just as small

My questions:
1) Can I use any prebuilt coil and swap the circuit from a larger one? I feel like there is a reason I can't!
2) Recommendations of specific coils?
Thank you so much!
