Weather minimal: common questions

What microcontroller does the Weather minimal use?

The Weather minimal is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Weather minimal PCB?

The Weather minimal measures 25.4 × 36.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Weather minimal?

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

Where can I download the Weather minimal design files?

From the pypilot/pypilot_schematics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Weather minimal design in my own project?

The repository has no license, so all rights stay with pypilot. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Weather minimal 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.
