Neuromorphic retina encoder: common questions

How big is the Neuromorphic retina encoder PCB?

The Neuromorphic retina encoder measures 140 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Neuromorphic retina encoder?

134 components, from 32 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 Neuromorphic retina encoder design files?

From the RyanHailey21/neuromorphic-retina-encoder-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 Neuromorphic retina encoder design in my own project?

The repository has no license, so all rights stay with RyanHailey21. Use it as a reference, and ask the author before reusing the design.
