J4 is a generic connector with 4 pins and DRV8871-2 is a motor driver with 4 pins as well. Without any specifics on what each pin on J4 is supposed to do, a basic suggestion for connecting J4 to DRV8871-2 can be made as follows:
  1. Connect J4:Pin_1 to DRV8871-2:IN1.
  2. Connect J4:Pin_2 to DRV8871-2:IN2.
  3. Connect J4:Pin_3 to DRV8871-2:VM providing it is the power supply for the motor.
  4. Connect J4:Pin_4 to DRV8871-2:GND.
Again, please check the purpose of each pins in the schematic and revise the connections if needed.

As an AI, I don't have the capability to visually inspect your Flux project for airwires. You need to utilize the design rule check (DRC) feature of Flux for that. The DRC will automatically detect and highlight any airwires in your design.
To do this, follow the steps:
  1. Click on the "Inspect" icon located on the left side panel.
  2. In the dropdown that appears, select "Check Design Rule".
  3. Wait for the DRC to complete, it will highlight any issues including airwires.
If you've found airwires and need advice on how to proceed, I can provide guidance. Could you specify the components and nets involved in the airwire?
