Iris-Project: common questions

What microcontroller does the Iris-Project use?

The Iris-Project is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Iris-Project PCB?

The Iris-Project measures 87.9 × 36.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iris-Project?

39 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Iris-Project design files?

From the aayu0-0/Iris-Project-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Iris-Project design in my own project?

The repository has no license, so all rights stay with aayu0-0. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Iris-Project 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.
