Smallest possible wireless charging coil
I want to mod my Nothing Ear (a) and “stick” a wireless charging coil underneath but on Aliex the smallest i could find was 10.6mm x 4.3mm and the bottom of the case is a ~6mm x ~4mm.
I’m looking for the wireless adapter with usbc for old phones, but i’m open to give a shit to a raw coil and a little bit of soldering for the usbc.
Anyone that can help me? I’m new af in these kind of projects.
