-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.

It does not have pass-throw holes for the expansion port connector. ​+The deck is designed to be installed as the last deck on the bottom of the Crazyflie 2.0.

-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.
