Carbon: common questions

What microcontroller does the Carbon use?

The Carbon is built around the ESP32-C6-MINI-1, from the ESP32 family.

How big is the Carbon PCB?

The Carbon measures 46.3 × 43.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Carbon?

31 components, from 17 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 Carbon design files?

From the Enderman8843/Carbon 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 Carbon design in my own project?

The repository has no license, so all rights stay with Enderman8843. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Carbon 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.
