Esp32tux mini: common questions

What microcontroller does the Esp32tux mini use?

The Esp32tux mini is built around the ESP32-C5, from the ESP32 family.

How big is the Esp32tux mini PCB?

The Esp32tux mini measures 26 × 26 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32tux mini?

55 components, from 49 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 Esp32tux mini design files?

From the tux-friend/tux-cube 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 Esp32tux mini design in my own project?

Yes, under the terms of its GPL-3.0 license, which tux-friend chose for the repository.

Can I test firmware for the Esp32tux mini 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.
