Hi all,
I'm building a synth with a Teensy 4.1 and have a question about power and USB. I'd like to have my breakout board feature an external USB B connector where I can program and get send/receive midi from the Teensy (like this one) and to also feed the Teensy 5V from a 7805 regulator circuit.
My plan:
1. Cut the VIN/VUSB trace on the Teensy.
2. Connect the GND and Vin pins to 0 and +5V from the regulator circuit.
3. Connect the USB B connector to the USB host pins in the middle of the Teensy
Will this setup work? Also, if I leave the USB Host 5V pin disconnected from the USB B connector, do I even need to cut the trace?
Thanks so much for any feedback.
