## 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 Adafruit thought it might be cool if your Arduino project can recharge itself wirelessly.

Adafruit have added a ton of Qi receivers but, until now, Adafruit haven't had a charging base.No longer! This is a super simple Qi transmitter.It will work with any standard Qi charger receivers.You just connect the board to a 5v power supply - either through a micro USB port - then put your device w/ Qi receive onto the base. If you want to 'share' the microUSB power connection, you can also connect direct to the USB-A port

Maximum output is around 5W which is good for most smart phones, basically 1000mA charge at 5V on the other side of the wireless connection.It has a charging distance of 2-8mm, works with all Adafruit's Qi charge receivers. You can only use one receiver per transmitter so if you want to charge two Qi devices at once, you'll need 2 transmitters.

Note: PCB may come in blue or green!
