the SWD lines and reset are required, SWO can be connected if you want to use ITM. This means:
- GND
- VCC
- SWIO
- SWCLK
- SWO (Optional)
- RESET

That corresponds to the connector P3 of the Crazyflie schematic: https://www.bitcraze.io/documentation/h ... _rev.b.pdf

Voltage of VCC?
SWIO means SWDIO?

The Crazyflie is a 3.0V system. Yes SWIO is SWDIO, its a typo in the schematic.
