Description
If you have a modern smart phone you may have noticed that it comes with built in wireless charging capability called 'Qi charging.' Qi is a trademark name for a thin and smart inductive charging system. Many large gadget companies have standardized on Qi, which means it's easy to find a charging dish and we thought it might be cool if your Arduino project can recharge itself wirelessly. Thus, we now have a Qi charging receiver module as seen here here.
This is just the inductive charging Qi receiver. It will work with any Qi charger base transmitter that will work well with any standard inductive charger base. Simply solder two wires to the V+ and Gnd pins on the Qi module and place the item you want charged onto a charging base. The receiver chip manages the coil so that you'll always get 5V and 500mA. If the coil is too far it will simply not activate at all. In our demo, we used a classic cell phone charger plate.
The driver chip is an integrated receiver called the BQ51013B from TI. Since its a Qi charger it can only be used with Qi transmitters! If you want a simpler inductive charger, check out our 5V charger set - it isn't Qi compatible but used together it works quite well!
