Questions
How big is the LoadCell PCB?
It measures 51.1 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoadCell use?
83 parts, built around the MCP6002-I/P and M20-8760242. 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 LoadCell KiCad files?
From the synthetos/KicadExample repository on GitHub, at the commit this page was made from: the board is LoadCell.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoadCell design in my own project?
Its repository states no licence, so its author keeps all rights: ask synthetos before reusing the design.
