MR-DOS/TDR_diploma_thesis
Time domain reflectometer. Includes Hardware, firmware and GUI in Octave. Also a diploma thesis.
It measures 44.7 × 74.8 mm and has 2 copper layers, 1.6 mm thick.
34 parts, built around the AMS1117. 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 Adem-ADATEPE/PCB repository on GitHub, at the commit this page was made from: the board is STM320F030K6T6_WINBOND_DEVELOPER/STM320F030K6T6_WINBOND_DEVELOPER.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Adem-ADATEPE before reusing the design.
