Questions
How big is the System testbed PCB?
It measures 182.6 × 41.8 mm and has 4 copper layers, 1.54 mm thick.
What parts does the System testbed use?
199 parts, built around the SKY13330-397LF, GRF5604 and TXS0101DBV. 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 System testbed KiCad files?
From the OpenAir-Lab/capstone-project repository on GitHub, at the commit this page was made from: the board is Hardware/KiCAD/system-testbed/system-testbed.kicad_pcb and its schematic Documentation/Reference Designs/Adafruit/TFT Display Module/Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the System testbed 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).
