Questions
How big is the PllTracker PCB?
It measures 44.6 × 52.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PllTracker use?
24 parts, built around the ATGM336H-5N31, MAX809STRG-TP and AO3401A. 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 PllTracker KiCad files?
From the Mineinjava/ffellowship repository on GitHub, at the commit this page was made from: the board is pllTracker/pllTracker.kicad_pcb and its schematic Bare_PICO_PCBA_UNUSED/dPicoTracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PllTracker design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mineinjava before reusing the design.
