The 80 most common of 82 parts.
It measures 87.2 × 71.3 mm and has 2 copper layers, 1.6 mm thick.
82 parts, built around the BME280, HPP845E131R5, MAX31855EASA+T and MC33063AD. 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 Lelk0e/DA_Sensorbox repository on GitHub, at the commit this page was made from: the board is Sensorbox_HW/SensorBox/SensorBox.kicad_pcb and its schematic Sensorbox_HW/SensorBox/SensorBox.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 Lelk0e before reusing the design.
