THW-Badge: common questions

What microcontroller does the THW-Badge use?

The THW-Badge is built around the ATmega328-P, from the AVR/Arduino family.

How big is the THW-Badge PCB?

The THW-Badge measures 84.9 × 82.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the THW-Badge?

44 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the THW-Badge design files?

From the lugsaar/THW-Badge repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the THW-Badge design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the THW-Badge 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.
