Questions
How big is the EffecitveRangeMic PCB?
It measures 24.4 × 18 mm and has 2 copper layers, 0.6 mm thick.
What parts does the EffecitveRangeMic use?
25 parts, built around the 54201-S08-05ALF and SPH0645LM4H-B. 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 EffecitveRangeMic KiCad files?
From the EffectiveRange/pcb-micdevice repository on GitHub, at the commit this page was made from: the board is effecitveRangeMic.kicad_pcb and its schematic effecitveRangeMic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EffecitveRangeMic design in my own project?
Its repository states no licence, so its author keeps all rights: ask EffectiveRange before reusing the design.
