Questions
How big is the Brewnode PCB PCB?
It measures 136.9 × 75.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brewnode PCB use?
87 parts, built around the ADS1115IDGS, PCF8574T, BSS138 and FDN340P. 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 Brewnode PCB KiCad files?
From the Tobbisch/Brewnode repository on GitHub, at the commit this page was made from: the board is Brewnode_PCB/Brewnode_PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brewnode PCB design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
