little board to help the teensy 3.6 boot in eurorack modules
Mount this little fellow underneath your Teensy 3.6 if you are having trouble booting when mounted in place of a Teensy 3.2 in a Eurorack module. The symptom is that the module never executes your code when booted without USB power.
This board adds a voltage supervisor that delays the start of the Teensy (via the Reset pin) until there is adequate power. It was designed to fit on the bottom of the board in an area that would not be populated for a Teensy 3.2.
You can always use Eagle to create your own Gerbers and select your own fab house.

Thanks to everyone there (especially neutron7) for finding the solution. All I did was panel the thing up. Saved my bacon on a project. :)
