Speaker: common questions
How big is the Speaker PCB?
The Speaker measures 73.8 × 60.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Speaker?
28 components, from 21 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 Speaker design files?
From the AbdullahHendy/Speaker-PCB 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 Speaker design in my own project?
The repository has no license, so all rights stay with AbdullahHendy. Use it as a reference, and ask the author before reusing the design.
