ET V6 is an open-source printed circuit board by FlorianvdDussen, from the FlorianvdDussen/ET_V6 repository on GitHub. It is a 2-layer board of 63.5 × 48.3 mm with 67 parts on 72 nets, routed with 314 tracks and 49 vias.
It is built around the TPS630702RNMR, CC0603KRX7R9BB104 and CL21A226MAYNNNE, with the 0603CG331J500NT, RR0816P-6341-D-78H and CL05B104KB54PNC among its other parts. Its parts include 29 capacitors, 21 resistors, 4 connectors, 3 ICs and 3 inductors. It belongs with the AVR (ATmega, ATtiny) boards of this library.
This Repo contains the files to re-use old photo-electric sensors to create a very responsive and accurate timing gate system close to Brower's or other commercial products. The goal of this project was to create a product that is easy to use and creates accurate timings for a Track&Field application, where very milisecond counts. Further documentation and photos can be found on florianvanderdussen.nl.

67 parts, built around the TPS630702RNMR, CC0603KRX7R9BB104, CL21A226MAYNNNE and 0603CG331J500NT. 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.
From the FlorianvdDussen/ET_V6 repository on GitHub, at the commit this page was made from: the board is KICAD/ET_V6.kicad_pcb and its schematic ET_V6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask FlorianvdDussen before reusing the design.
