Overview
Breakout is an open-source printed circuit board by UCDFS, from the UCDFS/Circuits repository on GitHub. It is a 2-layer board of 81.4 × 64.3 mm with 59 parts on 96 nets, routed with 218 tracks and 6 vias.
It is built around the SN65HVD230D, TEENSY 4.1 and TPS62163DSG, with the NUP3105L and VLS3015CX-2R2M-1 among its other parts. Its parts include 20 resistors, 12 connectors, 11 capacitors, 4 ICs and 2 transistors. It belongs with the interfaces and adapters boards and the ESP32 and NXP (LPC, Kinetis, i.MX RT) boards of this library.

Questions
How big is the Breakout PCB?
It measures 81.4 × 64.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Breakout use?
59 parts, built around the SN65HVD230D, TEENSY 4.1, TPS62163DSG and NUP3105L. 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 Breakout KiCad files?
From the UCDFS/Circuits repository on GitHub, at the commit this page was made from: the board is Teensy 4.1 Breakout Board/Breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask UCDFS before reusing the design.
