LIA: common questions
How big is the LIA PCB?
The LIA measures 290.9 × 87.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LIA?
295 components, from 130 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LIA design files?
From the JasMoH/Photoacoustic repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the LIA design in my own project?
Yes, under the terms of its GPL-3.0 license, which JasMoH chose for the repository.
