OEM Universal Qi Wireless Receiver Module

If you have a modern smartphone, you may have already noticed that it comes with a built-in wireless charging feature called Qi charging. Qi is a brand name for a thin and smart inductive charging system. Many major device manufacturers have standardized on Qi, which means it's easy to find a charging pad. It would be pretty cool if yours could do that too. The Arduino project can charge wirelessly. Now there is a Qi charging receiver module, as shown here. This is just the inductively charging Qi receiver. It works with any Qi charging base that complies with the standard. Simply solder two wires to the V+ and Gnd pins on the Qi module and place the desired item on a charging base. The receiver chip manages the coil, ensuring you always receive 5V and 500mA. If the coil is too far away, it simply won't activate. The driver chip is an integrated receiver called BQ51013B from TI. Since it is a Qi charger, it can only be used with Qi transmitters.
