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.
This is a 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!
New from Elmwood, we now offer a laser cut acrylic mounting kit! Included are two 160 mm x 70 mm pieces of clear or black laser cut acrylic with the proper holes and mounting hardware. Please note the pictures show our prototype, which has an M logo on it for demonstration purposes and a bottom wood layer (you will receive two Acrylic layers). Want your logo on it? Send us an email and we will let you know if we can do it.
