Questions
How big is the Instrumentation v3 PCB?
It measures 100 × 115 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Instrumentation v3 use?
157 parts, built around the OPA2310ID and PCA9306DP. 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 Instrumentation v3 KiCad files?
From the harrymander/fph-snippets-github repository on GitHub, at the commit this page was made from: the board is recap-instrumentation/hw/board-v3/instrumentation-v3.kicad_pcb and its schematic recap-instrumentation/hw/board-v2/instrumentation-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Instrumentation v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask harrymander before reusing the design.
