Questions
How big is the Tdr PCB?
It measures 60 × 37 mm and has 4 copper layers, 1.7 mm thick.
What parts does the Tdr use?
144 parts, built around the MCP4822-E/P, W25Q128JVPIQ, MIC5504-3.3YM5 and LD39050PUR. 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 Tdr KiCad files?
From the blazra/tdr repository on GitHub, at the commit this page was made from: the board is boards/TDR/TDR.kicad_pcb and its schematic boards/TDR/FPGA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tdr design in my own project?
Its repository states no licence, so its author keeps all rights: ask blazra before reusing the design.
