Questions
How big is the 2-Channel RPi Oscilloscope PCB?
It measures 101.8 × 63.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 2-Channel RPi Oscilloscope use?
148 parts, built around the OPA4191ID, THS4541YR, MCP4728-E/UN and ADG465BRM. 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 2-Channel RPi Oscilloscope KiCad files?
From the HapeMask/rpi_experiments repository on GitHub, at the commit this page was made from: the board is schematics/rpi_oscilloscope/2-Channel RPi Oscilloscope.kicad_pcb and its schematic schematics/rpi_oscilloscope/2-Channel RPi Oscilloscope.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 2-Channel RPi Oscilloscope design in my own project?
Its repository states no licence, so its author keeps all rights: ask HapeMask before reusing the design.
