Open Source Smart Glasses: common questions

What microcontroller does the Open Source Smart Glasses use?

The Open Source Smart Glasses is built around the 1904-1029-1-ND, from the RP2040/RP2350 family.

How big is the Open Source Smart Glasses PCB?

The Open Source Smart Glasses measures 93 × 10.5 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the Open Source Smart Glasses?

80 components, from 57 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 Open Source Smart Glasses design files?

From the aezrapour/RINSIGHT 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 Open Source Smart Glasses design in my own project?

Yes, under the terms of its MIT license, which aezrapour chose for the repository.

Can I test firmware for the Open Source Smart Glasses without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
