Porsche quad gauge: common questions

What microcontroller does the Porsche quad gauge use?

The Porsche quad gauge is built around the ATMEGA328P_TQFP, from the AVR/Arduino family.

How big is the Porsche quad gauge PCB?

The Porsche quad gauge measures 98 × 98 mm and is 1.6 mm thick.

How many components are on the Porsche quad gauge?

57 components, from 18 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 Porsche quad gauge design files?

From the Evancli/porsche-quad-gauge repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Porsche quad gauge design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which Evancli chose for the repository.

Can I test firmware for the Porsche quad gauge without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
