Morse mesh: common questions
How big is the Morse mesh PCB?
The Morse mesh measures 229.7 × 135.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Morse mesh?
61 components, from 39 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 Morse mesh design files?
From the eihli/morse-mesh 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 Morse mesh design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
