Level-Amp: common questions

How big is the Level-Amp PCB?

The Level-Amp measures 80.3 × 19.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Level-Amp?

11 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Level-Amp design files?

From the cscott/rain-barrel repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Level-Amp design in my own project?

The repository has no license, so all rights stay with cscott. Use it as a reference, and ask the author before reusing the design.
