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 Raspberry Pi project or cell phone with a microUSB port can recharge itself wirelessly. Thus, we now have four different MicroUSB Modules for different phone orientations.

This is the 85mm Forward version of our different Qi MicroUSB Modules. We also have a 20mm Forward, 20mm Reverse, and an 85mm Reverse.

Check out the big photo above of the microUSB connector orientation to determine which module you need!
We have a generic photo showing how the module sticks to the back of our Android phone, but you’ll have to check the MicroUSB connector orientation to determine which length/type of Qi module you need.
You do need a Qi transmitter to go along with the receivers — which we now carry in the Adafruit store.
