271 parts, built around the RP2040, W25Q16JVSSIQ, ADS1015IDGS and TXS0104EDR(LX). 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 krishchan007/DUT_Interface_board_v0.2 repository on GitHub, at the commit this page was made from: the board is DUT_Interface_board_v0.2.kicad_pcb and its schematic DUT_Interface_board_v0.2.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 krishchan007 before reusing the design.
