Hello,
I am trying to rebuild the teensy 3.2, but my final project will use an external power source that is not my laptop powering the device. In order to prevent current flowing back into my computer while programming, I know one method is to cut the solder jumper and sever the connection between the micro USB and Vin. However, after VBUS is routed through the fuse could I also just connect the fuse to ground and then not include the solder jumper at all in my design? Or would that cause some other issue.
I have included a photo of my schematic as it is currently and then what it would look like after I disconnected VBUS from VIN.
