This port has two analog inputs that can be used to connect analog sensors such as voltage, current, analog airspeed sensor... It can also be used to connect a sonar, but that functionality currently isn't implemented.
The conector connector used is a 4pin JST-SH.

The flight controller presents itself to the PC as a HID (Human Interface Device) and VCP (Virtual Comm Com Port) device.
The HID part comes configured for telemetry and is used to configure, update and debug your flight controller.
The VCP can be used for telemetry and CommBridge ComBridge functionality which binds Main or Flexi port to be used as a comm com port from your PC (useful for configuring your OSD without needing to rip it out of your airframe)
...
This port is used by developers for flashing and debuging debugging the firmware. Most users will never have to use it.
