README
README.mdProject Status
3dmodels/: Iteration 1 complete; iteration 2 WIP- Considering different potentiometer & button models (pot.s too small for knobs)
- Looking into overhead enclosure for button/knob interface (i.e., transitioning from partially exposed to fully enclosed)
firmware/: Iteration 1 WIP- Currently troubleshooting issues with SPI comm.; assumed resolution w/ the inclusion of tri-state buffer
- Potentiometers laggy; assumed resolution w/ swap for rotary encoders
hardware/: Iteration 1 complete; iteration 2 WIP- Adjustments needed to account for pullups/pulldowns & tri-state buffer
- Considering swapping potentiometers for rotary encoders & using different buttons
- Potentially re-evaluate netclasses/copper trace thicknesses
- Flip around opAmp (for some reason was inverted in schematics)
- Ensure all passives' values actually exist (if not, modify circuit to use ones that do)
- Swap 5V LDO to buck converter (& generally re-evaluate power distribution method (currently not adequate for long-term usage))

Questions
How big is the Jd2oscope PCB?
It measures 83 × 120 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Jd2oscope use?
61 parts, built around the ADS7279IPW, 3362P-1-103LF, KMR731NGLFS and CONBNC001. 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 Jd2oscope KiCad files?
From the Niftion/jd2oscope repository on GitHub, at the commit this page was made from: the board is hardware/jd2oscope/jd2oscope.kicad_pcb and its schematic hardware/jd2oscope-extra/Front_End_controls/Front_End_controls.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jd2oscope design in my own project?
Its repository states no licence, so its author keeps all rights: ask Niftion before reusing the design.
