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.

We've added a ton of Qi receivers but until now we haven't had a charging base. No longer! This is a super simple Qi transmitter. It will work with any standard Qi charger receivers - like the ones we carry here. 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 our 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!
