Universal Qi Wireless Charging Transmitter

Universal Qi Wireless Charging Transmitter info

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.

Universal Qi Wireless Charging Transmitter 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 through a micro USB then put your device with Qi receiver onto the base. If you want to 'share' the microUSB power connection, you can also connect direct to the USB-A port

Maximum output of Universal Qi Wireless Charging Transmitter 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.
