Mfo: common questions
How big is the Mfo PCB?
The Mfo measures 19 × 15.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mfo?
21 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mfo design files?
From the owen-rp2a03/mfo repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mfo design in my own project?
The repository has no license, so all rights stay with owen-rp2a03. Use it as a reference, and ask the author before reusing the design.
