Questions
How big is the Track node PCB?
It measures 45 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Track node use?
65 parts, built around the STM32F411CEU6, E73-2G4M08S1C, BME280 and TPS63802DLAR. 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 Track node KiCad files?
From the Malibushko/TrackNode repository on GitHub, at the commit this page was made from: the board is hardware/kicad/track-node/track-node.kicad_pcb and its schematic hardware/kicad/track-node-usb/track-node-usb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Track node design in my own project?
Its repository states no licence, so its author keeps all rights: ask Malibushko before reusing the design.
