Questions
How big is the Ecu emu PCB?
It measures 51.3 × 16.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ecu emu use?
38 parts, built around the E-L9637D, AMS1117-ADJ, BSP742R and 1N5819HW-7-F-01. 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 Ecu emu KiCad files?
From the Zulljon/ecu_emu repository on GitHub, at the commit this page was made from: the board is ecu_emu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ecu emu design in my own project?
Its repository publishes it under the LGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
