Questions
How big is the UltrasonicTRSwitch Tester PCB?
It measures 106.3 × 54.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the UltrasonicTRSwitch Tester use?
60 parts, built around the MAX4937CTN+, MIC5205-5.0YM5 and MIC5501-3.0YM5-TR. 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 UltrasonicTRSwitch Tester KiCad files?
From the keionbis/UltrasonicTRSwitchDevBoard repository on GitHub, at the commit this page was made from: the board is UltrasonicTRSwitch_Tester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UltrasonicTRSwitch Tester design in my own project?
Its repository states no licence, so its author keeps all rights: ask keionbis before reusing the design.
