    Teensy 3.2 USB Resistors

    I am making a custom Teensy 3.2 and am planning on using a TVS Diode on the data lines (specifically a SR05-02CTG) and was wondering if I need the two 33ohm resistors on the data lines (USBP, USBM) even if I have the TVS, feedback would be much appreciated

    Side Note - Has PJRC considered making a discord server?
