Questions

How big is the Board main PCB?

It measures 105.5 × 83 mm and has 4 copper layers, 1.45 mm thick.

What parts does the Board main use?

87 parts, built around the SN74LVC245APWR(LX), ADA4807-1AKSZ-R7, CD4001BM96 and SN74HC74DR(LX). 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 Board main KiCad files?

From the bmurmann/EE628 repository on GitHub, at the commit this page was made from: the board is 6_Test/3_PCB/test_board/board_main.kicad_pcb and its schematic 6_Test/3_PCB/test_board/board_main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Board main 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).
