Check out our www.bvmvent.org for updates.
The Problem: The COVID-19 Pandemic has highlighted the scarcity of potentially life-saving resources around the world.
Our Challenge: Design and Engineer an Open Source, low cost (sub $150) ventilator using readily available materials for rapid deployment in developing countries where there may not be an alternative.
Who we are: A Collective of Engineers, Medics and Scientists from across the world, centred around a hub in Phnom Penh, Cambodia. Help Us: We need Volunteers, a Community of Contributors and Donors to join us and help us deliver our vision.

Questions
How big is the LIBV PCB?
It measures 82 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LIBV use?
127 parts, built around the ATMEGA328-AU, CP2102N-A01-GQFN28R, 74HC244D and AMS1117-5.0. 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 LIBV KiCad files?
From the LIBVproject/LIBV-ventilator-pcb repository on GitHub, at the commit this page was made from: the board is LIBV MAIN Controller/LIBV/LIBV.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LIBV 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).
