About
Current Version: R0.1-V3
Omi Glass DevKit is based around the ESP32-S3 & OV2640, adding image capture to the Omi AI platform. For modularity, we selected the Xiao ESP32-S3 Sense microcontroller breakout. It also has an onboard microphone & microSD reader.

Questions
How big is the Omi Glass DevKit PCB?
It measures 25.5 × 19.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Omi Glass DevKit use?
8 parts. 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.
Where can I download the Omi Glass DevKit KiCad files?
From the LyndLabs/Omi-Glass-DevKit repository on GitHub, at the commit this page was made from: the board is pcb/Omi-Glass-DevKit.kicad_pcb and its schematic pcb/Omi-Glass-DevKit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Omi Glass DevKit design in my own project?
Its repository states no licence, so its author keeps all rights: ask LyndLabs before reusing the design.
