-The Qi wireless charging expansion board allow to charge the Crazyflie 2.0 using a standard Qi wireless charger. The board is designed to privide up to 1A which means that the charging speed should be equivalent as when using USB to charge. Using a wireless charger is convenient (just put the copter on the charger and pick it up later charged) but mostly it allows new interesting use case like autonomously landing on the charger for extended autonomous flight system.+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.
-This expansion board has few Crazyflie 2.0-specific components, so it can be used as a wireless-5V power supply for other project.+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
-The board works by injecting 5V in the Crazyflie 2.0 VUSB line. In consequence it is recommended not to connect the Crazyflie to a 5V USB charger while the Qi expansion board is installed. Furthermore connecting a USB charger while the Qi-equipped crazyflie 2.0 is put on a wireless charger must be avoided.+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 consequenceit 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 Qi-equipped Crazyflie 2.0 is sitting on a wireless charger.
