Wireless power transfer modules (with schematic)

Some very small modules designed to transfer power wirelessly for battery charging or direct powering of sealed devices. The power transfer is low, but perfectly suitable for low current devices. Standby current with no load is about 24mA at 5V, so about a tenth of a watt. For best coupling the antennas have to be close together, so cases should be thin and flat, preferably with an alignment guide. The reason the normal wireless LEDs wouldn't light with this coil is due to their tuned LC circuit being optimised for a different frequency. My simple coil with inverse parallel LEDs will work at a wide range of frequencies. Here's the AliExpress listing I got these from:- https://www.aliexpress.com/item/10050...
