87 parts, built around the SN65LBC176QDRQ1, TCAN1057AEVDRQ1, INA238AQDGSRQ1 and MAX31856MUD+T. 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 yrromero04/HEDGE2-SCI_PCB repository on GitHub, at the commit this page was made from: the board is HEDGE2-SCI-main/HEDGE2-SCI.kicad_pcb and its schematic HEDGE2-SCI-main/HEDGE2-SCI.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 yrromero04 before reusing the design.
