I'm trying to make a device that uses the Teensy 3.5 with specific I/O and powering options. My lab uses this device to calculate an animal's position/velocity from an incoming rotary encoder, and it can also read USB serial data to output specifically shaped voltage signals. I have a power jack option in case we are using an unpowered USB hub, which would not supply enough current to the Teensy. You can see in the schematic that I am trying to use diode or-ing logic to choose among up to 3 voltage sources (USB, power jack & rotary encoder).
The board will go in this case: https://www.mouser.com/ProductDetai...piMZZMv151B%2BVDR3zLRriE50y2dfJPKc%2BIEwPrg%3 and use this usb extension: https://www.digikey.com/en/products/detail/adafruit-industries-llc/3258/6238006
I appreciate any and all feedback. One possible issue is that the DRC doesn't like the vias I'm putting under the voltage regulator saying that they overlap.
