5W / 15W Wireless Charging Transmitter Modules

Micro-USB 5 W (45 mm coil) and Type-C 15 W (42 mm coil).

Two compact embedded transmitters: a 5 W Micro-USB version with a 45 mm coil and a 15 W USB Type-C version with a 42 mm coil. Each pairs a slim control PCB with a separate planar coil and can be used with phones that support wireless charging or with a matching receiver.
