Questions
How big is the Pmod level conv-2 PCB?
It measures 83 × 22.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pmod level conv-2 use?
71 parts, built around the SN74LVC1T45DBV. 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 Pmod level conv-2 KiCad files?
From the TomKeddie/prj-pmod repository on GitHub, at the commit this page was made from: the board is hardware/pmod-level-conv-2/pmod-level-conv-2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pmod level conv-2 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).
