Questions

How big is the GPS MINPOINT PCB?

It measures 64.8 × 74.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the GPS MINPOINT use?

20 parts, built around the PIC24FJ64GA002-I/SP. 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 GPS MINPOINT KiCad files?

From the cecilsmith/GPS-MINPOINT repository on GitHub, at the commit this page was made from: the board is 3_Hardware/KiCad/GPS-MINPOINT.kicad_pcb and its schematic 3_Hardware/KiCad/GPS-MINPOINT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the GPS MINPOINT design in my own project?

Its repository states no licence, so its author keeps all rights: ask cecilsmith before reusing the design.
