About the Espglasses PCB

Espglasses is an open source ESP32 PCB design by mozaikuu, published on GitHub. It is a 2-layer board measuring 180 × 50 mm, with 22 components from 16 distinct parts.

Its main chip is the ESP32_WROVER_E_CORE, from the ESP32 family. Other key parts include the OV2640_CAMERA_IF, MPU6050_CORE, INMP441_CORE, LIION_CHARGER_IC_CORE and REGULATOR_3V3_CORE. By type, the board carries 8 ICs, 5 capacitors, 5 resistors, 3 connectors and 1 diode.

From the project

AR_Glasses (Temp)

This workspace was reorganized into a clean, role-based layout focused on a single Python backend and multiple client integrations.

- Keep one launcher at project root: start.py. - Core runtime code should live under app/. - Clients should consume APIs only (no direct imports from internal modules).

All Smart Bus Tracking MVP modules are grouped under bussystem/` for easier access:

Espglasses: common questions

What microcontroller does the Espglasses use?

The Espglasses is built around the ESP32_WROVER_E_CORE, from the ESP32 family.

How big is the Espglasses PCB?

The Espglasses measures 180 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Espglasses?

22 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Espglasses design files?

From the mozaikuu/CEREBRO-AI-Smart-Glasses-for-Indoor-Navigation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Espglasses design in my own project?

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

Can I test firmware for the Espglasses 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.
