LED board: common questions
How big is the LED board?
The LED board measures 39 × 39 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LED board?
15 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the LED board design files?
From the ocean-discovery-league/maka-niu-design-files repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the LED board design in my own project?
The repository has no license, so all rights stay with ocean-discovery-league. Use it as a reference, and ask the author before reusing the design.
