Ocatvia-Carbon I-C Challenge: common questions

What microcontroller does the Ocatvia-Carbon I-C Challenge use?

The Ocatvia-Carbon I-C Challenge is built around the ESP32-S3-WROOM-2-N16R8V, from the ESP32 family.

How many components are on the Ocatvia-Carbon I-C Challenge?

24 components, from 15 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 Ocatvia-Carbon I-C Challenge design files?

From the Hokkyokuse1/Ocatvia-Carbon_I-C_Challenge repository on GitHub, which has a netlist and the BOM; the links under Design files point to each one.

Can I use the Ocatvia-Carbon I-C Challenge design in my own project?

The repository has no license, so all rights stay with Hokkyokuse1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Ocatvia-Carbon I-C Challenge 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.
