Travis num2024: common questions

What microcontroller does the Travis num2024 use?

The Travis num2024 is built around the Arduino Pro Micro, from the AVR/Arduino family.

How big is the Travis num2024 PCB?

The Travis num2024 measures 85.2 × 137.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Travis num2024?

81 components, from 8 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 Travis num2024 design files?

From the dieseltravis/travis-ergogen-numpad repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Travis num2024 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Travis num2024 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.
