From the project

Contains the Nyx flight computer family developed for UNSW Rocketry Avionics team.

How to use: - Make a local clone of the entire repositry - Open the project you want from the file it is in - Enjoy!

To add parts to the library: - All parts go in the UNSW Rocketry parts folder (single parrts library) - Open a project and add the symbol into the UNSW Rocketry Library (symbol library, via import) - Put the footprint in the footprints.pretty folder of the parts folder - Put the 3D model in the 3D models folder - In the project, edit the symbol you have imported and assign the default footprint to the footprints.pretty folder footprint (.kicad_mod) - Edit the footprint you…

IrisV1: common questions

What microcontroller does the IrisV1 use?

The IrisV1 is built around the ESP32-S3-WROOM-1U-N4, from the ESP32 family.

How big is the IrisV1 PCB?

The IrisV1 measures 36.7 × 75 mm, has 2 copper layers and is 1.596 mm thick.

How many components are on the IrisV1?

79 components, from 34 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 IrisV1 design files?

From the HomeOnDuna/Nyx-Flight-Computers 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 IrisV1 design in my own project?

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

Can I test firmware for the IrisV1 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.
