From what I understand, I can connect a diode between VUSB and VIN (?) to have the Teensy automatically use the higher voltage (USB power vs external), but I'm planning to use a 5v external power source.
Is it possible to have a 5v external power source and ALWAYS use that if it's connected but otherwise use the USB power? That would help me during development, but when I move the device into "production" I'd like to power it using external power (but keep USB connected for data).
Thanks
