Questions
How big is the Secant PCB?
It measures 70.1 × 45.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Secant use?
55 parts, built around the TM4C123GE6PMI, NCV7356D1, TJA1051T and TLV70033QDDCRQ1. 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 Secant KiCad files?
From the ericevenchick/secant repository on GitHub, at the commit this page was made from: the board is hw/secant.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Secant design in my own project?
Its repository states no licence, so its author keeps all rights: ask ericevenchick before reusing the design.
