Hardware
This board provides standard MIDI IN, OUT, and THRU ports that connect to the PJRC Teensy 3.2 development board. Connections follow the MIDI standard -- i.e. optoisolation on the IN port, standard 5mA signals, etc. For more information, see the MIDI 1.0 Specification.
In addition, all pins on the perimeter of the Teensy are broken out for easier access and prototyping. Footprints for a 5V, 1A regulator and associated components are provided for stand-alone operation.
Warning: Disconnect external power source when connected to USB.
Connections
MIDI_IN is connected to D0/RX1 for use with the Serial1 library.
MIDI_OUT is connected to D1/TX1, ditto with Serial1.

Questions
How big is the TMIDI PCB?
It measures 59 × 61.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TMIDI use?
28 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TMIDI KiCad files?
From the calcium3000/TeensyMIDIInterface repository on GitHub, at the commit this page was made from: the board is hardware/TMIDI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TMIDI design in my own project?
Its repository states no licence, so its author keeps all rights: ask calcium3000 before reusing the design.
