About the Iris-Intern PCB

Iris-Intern is an open source ESP32 PCB design by aayu0-0, published on GitHub. It is a 2-layer board measuring 87.9 × 36.8 mm, with 39 components from 23 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the TPS563202S. By type, the board carries 14 capacitors, 11 resistors, 4 connectors, 3 diodes, 2 ICs and 2 switches.

From the project

The project was executed in a team-based environment (5 members) with a strong focus on real-world system design practices, including modular architecture, hardware–software co-design, and scalable development.

The project was executed in a team-based environment (5 members) with a strong focus on real-world system design practices, including modular architecture, hardware–software co-design, and scalable development.

The aim was not only to build a functional autonomous system, but to design it the way industry-grade autonomous platforms are actually engineered.

Iris-Intern: common questions

What microcontroller does the Iris-Intern use?

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

How big is the Iris-Intern PCB?

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

How many components are on the Iris-Intern?

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

Where can I download the Iris-Intern design files?

From the aayu0-0/Iris-Intern 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-Intern 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-Intern 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.
