Crazyflie schematics

Hi!

I have a doubt about the Crazyflie schematics. It's about the MOSFET on the motors. I guess the electricity comes from +BATT and goes to ground so Souce of the MOSFET should be on the top, connected to +BAT, and Drain should be on the bottom, connected to Ground. However, on the schematics, Drain is connected to +BATT and Source is connected to ground which I think is an error because the MOSFET is inverted. I'm probably wrong but I'd like to know why is the MOSFET placed like that.

Thank you very much!

It's a N-Channel MOSFET for which you connect source to ground. You can find an explanation here.
