Hi everyone,
I have a Teensy 4 powered from a 7.4V battery, that goes into to a 5V regulator. The 7.4V battery also powers 3 motors directly.
When I have the teensy powered by a USB I've noticed the motors are also drawing power back through the regulator from the Teensy. I understand I could add a Schottky diode at the 5V line of the regulator to prevent this or a mechanical switch.
Questions:
Thanks for any tips or suggestions

Questions:
- Does anyone know a better method (lower voltage drop, less power lost when using battery) they could recommend?
