Present Day: common questions
How big is the Present Day PCB?
The Present Day measures 110 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Present Day?
184 components, from 76 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 Present Day design files?
From the nxvxr14/control-celda-fts-mecatronica-UNAB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Present Day design in my own project?
The repository has no license, so all rights stay with nxvxr14. Use it as a reference, and ask the author before reusing the design.
