Questions
How big is the Attempt2 PCB?
It measures 71.5 × 54.4 mm and has 4 copper layers, 1.77 mm thick.
What parts does the Attempt2 use?
60 parts, built around the MAX2686LEWS+T, NRF9151-LACA-R7, CP2102N-A02-GQFN24R and MCP73831T-2ACI/OT-HXY. 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 Attempt2 KiCad files?
From the m3llo0n/stat-pcb repository on GitHub, at the commit this page was made from: the board is attempt2.kicad_pcb and its schematic PCB downloads/stat project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Attempt2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask m3llo0n before reusing the design.
