Questions
How big is the Cb flex PCB?
It measures 81 × 76 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cb flex use?
89 parts, built around the BMP180, MCP1640B-I/MC, TSL2561T and AP7365-30WG. 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 Cb flex KiCad files?
From the panStamp/kicad repository on GitHub, at the commit this page was made from: the board is cb-flex/cb-flex.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cb flex design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
