Universal Qi Wireless Charging Transmitter

Description

If you have a modern smartphone, you'll have noticed that they come with a wireless charging system called 'Qi charging'. Qi is a trademark name of a thin and intelligent inductive charging system. Many large gadget companies have standardized on Qi, which means it's easy to find a charging pad and we thought it might be nice if your Arduino project can recharge wirelessly. We've added a lot of Qi receivers, but, until now, we haven't had a charging base. No more! This is a super simple Qi transmitter. It will work with all standard Qi charger receivers - like the ones we carry here. Simply connect the board to a 5v power supply - via a micro USB port - then put your device w/ Qi receive on the base. If you want to share the microUSB power connection, you can also connect directly to the USB-A port Maximum output is about 5W which is good for most smart phones, basically charging 1000mA at 5V on the other side of the wireless connection. It has a charging distance of 2-8mm, works with all our Qi charging receivers. You can only use one receiver for each transmitter, so if you want to charge two Qi devices at once, you'll need 2 transmitters.
