Questions
How big is the OutdoorMeasureUnit PCB?
It measures 86 × 78 mm and has 4 copper layers, 1.6 mm thick.
What parts does the OutdoorMeasureUnit use?
51 parts, built around the NRF24L01P-R, TPS62840DLCR, BMP280 and TSL2561T. 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 OutdoorMeasureUnit KiCad files?
From the Tepetop/Weather-Station repository on GitHub, at the commit this page was made from: the board is outdoorPCB/OutdoorMeasureUnit.kicad_pcb and its schematic outdoorPCB/OutdoorMeasureUnit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OutdoorMeasureUnit design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tepetop before reusing the design.
