Questions
How big is the Kicad snapshot step16 rev a layout complete 20260324 150352 PCB?
It measures 249 × 180.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kicad snapshot step16 rev a layout complete 20260324 150352 use?
91 parts, built around the ADM2587EBRWZ-REEL7, ESP32-S3-WROOM-1U-N16R8, ISO1042BDWVR and MDBT50Q-1MV2. 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 Kicad snapshot step16 rev a layout complete 20260324 150352 KiCad files?
From the jgrano/Nx-PCBA repository on GitHub, at the commit this page was made from: the board is hardware/kicad/snapshots/kicad_snapshot_step16_rev-a-layout-complete_20260324_150352/nx.kicad_pcb and its schematic hardware/kicad/nx.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kicad snapshot step16 rev a layout complete 20260324 150352 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jgrano before reusing the design.
