About the Omi-Glass-DevKit PCB

Omi-Glass-DevKit is an open source ESP32 PCB design by LyndLabs, published on GitHub. It is a 2-layer board measuring 25.5 × 19.5 mm, with 7 components from 4 distinct parts.

Its main chip is the XIAO-ESP32S3-SMD, from the ESP32 family. By type, the board carries 3 connectors, 2 resistors, 1 IC and 1 switch.

PCB's for Omi Glass

R0.0-Vx - V2 glasses use EVQPUL\C, V3 uses EVQP7L\C buttons to reduce size. - V2 production files not provided or recommended for production. - R0.0 designs contain minor issues that are rectified / bodged in production, R0.1 files are provided for archive but were never fabricated.

R0.2-V3 - switches back to EVQPU series buttons (bc Ro is fussy) - delete jumper

Omi-Glass-DevKit: common questions

What microcontroller does the Omi-Glass-DevKit use?

The Omi-Glass-DevKit is built around the XIAO-ESP32S3-SMD, from the ESP32 family.

How big is the Omi-Glass-DevKit PCB?

The Omi-Glass-DevKit measures 25.5 × 19.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Omi-Glass-DevKit?

7 components, from 4 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 Omi-Glass-DevKit design files?

From the LyndLabs/Omi-Glass-DevKit 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 Omi-Glass-DevKit design in my own project?

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

Can I test firmware for the Omi-Glass-DevKit without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
