Gmm: common questions
How big is the Gmm PCB?
The Gmm measures 50 × 75 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Gmm?
240 components, from 78 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 Gmm design files?
From the GMM-7550/gmm7550-hardware 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 Gmm design in my own project?
The repository has no license, so all rights stay with GMM-7550. Use it as a reference, and ask the author before reusing the design.
