Questions
How big is the Serialcommunicationmod PCB?
It measures 115 × 56.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Serialcommunicationmod use?
110 parts, built around the MCP2551-I/SN, LM324, AMS1117-3.3 and LM7805. 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 Serialcommunicationmod KiCad files?
From the ZeniteSolar/MSR22 repository on GitHub, at the commit this page was made from: the board is hardware/serialcommunicationmod.kicad_pcb and its schematic hardware/analog.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Serialcommunicationmod 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).
