Computer Vision-Based Tactile Feedback for the Visually Impaired
Grove - Vision AI Module V2 is an open-source printed circuit board by aram-ap, from the aram-ap/daredevil repository on GitHub, published under the MIT licence. It is a 4-layer board of 40 × 20 mm with 114 parts on 98 nets, routed with 880 tracks and 275 vias.
It is built around the SY80004DQD, CH343P and W25Q128JWSIQ, with the DF2S6.8FS,L3M, CJ1012 and RC0402JR-074K7L among its other parts. Its parts include 36 capacitors, 33 resistors, 17 diodes, 6 ICs and 5 transistors.
This is the library for Grove Vision AI V2 and its case.

You can find the case here as well.

It measures 40 × 20 mm and has 4 copper layers, 1.2 mm thick.
114 parts, built around the SY80004DQD, CH343P, W25Q128JWSIQ and DF2S6.8FS,L3M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the aram-ap/daredevil repository on GitHub, at the commit this page was made from: the board is hardware/wrist_module/Library/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_pcb and its schematic hardware/wrist_module/Library/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
