7seg control: common questions

How big is the 7seg control PCB?

The 7seg control measures 50.8 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 7seg control?

44 components, from 20 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 7seg control design files?

From the 7m4gmh/7seg-panel 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 7seg control design in my own project?

The repository has no license, so all rights stay with 7m4gmh. Use it as a reference, and ask the author before reusing the design.
