Questions
How big is the Signal enhancer PCB?
It measures 105.5 × 91.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Signal enhancer use?
25 parts, built around the SN74LS74AN, 74HC14 and NE555P. 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 Signal enhancer KiCad files?
From the neuroMoth/3-Port-Bpod-Rig repository on GitHub, at the commit this page was made from: the board is Circuitry/signal-enhancer/signal-enhancer.kicad_pcb and its schematic Circuitry/signal-enhancer/signal-enhancer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Signal enhancer 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).
