Tuxmini v03: common questions

What microcontroller does the Tuxmini v03 use?

The Tuxmini v03 is built around the ESP32-C5, from the ESP32 family.

How big is the Tuxmini v03 PCB?

The Tuxmini v03 measures 32 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tuxmini v03?

78 components, from 47 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 Tuxmini v03 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 Tuxmini v03 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 Tuxmini v03 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.
