Weather sensors: common questions

What microcontroller does the Weather sensors use?

The Weather sensors is built around the ATmega32A-AU, from the AVR/Arduino family.

How big is the Weather sensors PCB?

The Weather sensors measures 75.1 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Weather sensors?

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

Where can I download the Weather sensors 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 sensors 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 sensors 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.
