+====== Qi Wireless charging expansion deck ======
+The Qi wireless charging expansion deck allows charging the Crazyflie 2.0 battery with a standard Qi wireless charger. The deck is designed to provide up to 1A which means that the charging speed should be equivalent to USB charging. Using a wireless charger is convenient (just put the Crazyflie on the charger and pick it up later once charged) but mostly it allows new and interesting use cases such as autonomously landing on the charger to enable an extended autonomous flight system.
+The deck is designed to be installed as the last deck on the bottom of the Crazyflie 2.0. It does not have pass-through holes for the expansion port connector.
+This expansion deck has very few Crazyflie 2.0-specific components, so it can still be used as a wireless 5V power supply for other projects.
+The deck works by injecting 5V into the Crazyflie 2.0 VUSB line. As a consequence, it is not recommended to connect the Crazyflie to a 5V USB charger while the Qi expansion deck is installed. Furthermore, do not connect a USB charger while a Qi-equipped Crazyflie 2.0 is sitting on a wireless charger.
