Questions
How big is the GPSDOMonitor PCB?
It measures 150 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GPSDOMonitor use?
49 parts, built around the MCP16301T-I/CHY-MS, SN74HC595BRWNR, CRGCQ0402F68R and UMK105B7104KV-FR. 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 GPSDOMonitor KiCad files?
From the sergeyvfx/GPSDOMonitor repository on GitHub, at the commit this page was made from: the board is GPSDOMonitor/hardware/GPSDOMonitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GPSDOMonitor design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
