The KiCad project lives in the DEFOR111/MADHEX-v2 repository on GitHub; these links point at the commit this page was built from.

MADHEX-v2: common questions

What microcontroller does the MADHEX-v2 use?

The MADHEX-v2 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the MADHEX-v2 PCB?

The MADHEX-v2 measures 53 × 85 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MADHEX-v2?

75 components, from 36 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 MADHEX-v2 design files?

From the DEFOR111/MADHEX-v2 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 MADHEX-v2 design in my own project?

The repository has no license, so all rights stay with DEFOR111. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MADHEX-v2 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.
