Brucon: common questions

What microcontroller does the Brucon use?

The Brucon is built around the ESP32-S2-MINI-2-N4, from the ESP32 family.

How big is the Brucon PCB?

The Brucon measures 0.1 × 0 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Brucon?

693 components, from 28 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 Brucon design files?

From the jorisplusplus/brucon 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 Brucon design in my own project?

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

Can I test firmware for the Brucon 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.
