Questions
How big is the EffecitveRangeMic2 PCB?
It measures 65 × 30 mm and has 4 copper layers, 0.8 mm thick.
What parts does the EffecitveRangeMic2 use?
42 parts, built around the GSF7002DW, PIC18F16Q20-I/REB, SN74CBTLV3257RSVR and RT0402DRE075K3L. 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 EffecitveRangeMic2 KiCad files?
From the EffectiveRange/pcb-micdevice2 repository on GitHub, at the commit this page was made from: the board is effecitveRangeMic2.kicad_pcb and its schematic effecitveRangeMic2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EffecitveRangeMic2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EffectiveRange before reusing the design.
