This product is a low-power (wireless) power transmission module that can be integrated into your projects. This technology is increasingly used lately, being used even in smartphones.
Even if the big advantage is that we don't need any kind of connection between the two sides, which can be masked by any non-ferrous surface, we have a drawback, that of the yield, which is about 40%.
The module is designed to provide a fixed output voltage, stabilized at 5V, providing a maximum current of 500mA, depending on the distance between the coils.
If the small current works, increase the number of receiving coil turns to increase the transmission distance.
