OpenWeatherStation: common questions

What microcontroller does the OpenWeatherStation use?

The OpenWeatherStation is built around the STM32F107VCTx, from the STM32 family.

How big is the OpenWeatherStation PCB?

The OpenWeatherStation measures 50 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenWeatherStation?

107 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the OpenWeatherStation design files?

From the VitalSeptfonds/OpenWeatherStation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the OpenWeatherStation design in my own project?

Yes, under the terms of its MIT license, which VitalSeptfonds chose for the repository.

Can I test firmware for the OpenWeatherStation without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
