The KiCad project lives in the shields-jena-lena/low-power-weather-station repository on GitHub; these links point at the commit this page was built from.

Low power weather station: common questions

What microcontroller does the Low power weather station use?

The Low power weather station is built around the Socket_DIP-28_7.62mm_Conn, from the AVR/Arduino family.

How big is the Low power weather station PCB?

The Low power weather station measures 83.8 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Low power weather station?

38 components, from 34 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 Low power weather station design files?

From the shields-jena-lena/low-power-weather-station repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Low power weather station design in my own project?

Yes, under the terms of its GPL-3.0 license, which shields-jena-lena chose for the repository.

Can I test firmware for the Low power weather station 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.
