WolkenThermometer: common questions

What microcontroller does the WolkenThermometer use?

The WolkenThermometer is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the WolkenThermometer PCB?

The WolkenThermometer measures 36 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WolkenThermometer?

52 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the WolkenThermometer design files?

From the KarlZeilhofer/WolkenThermometer-kicad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the WolkenThermometer 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 WolkenThermometer 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.
