WeatherStation: common questions
What microcontroller does the WeatherStation use?
The WeatherStation is built around the ESP8266EX, from the ESP8266 family.
How big is the WeatherStation PCB?
The WeatherStation measures 87.9 × 71.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the WeatherStation?
163 components, from 66 distinct parts. The full bill of materials is listed on this page.
Where can I download the WeatherStation design files?
From the aleksul/WeatherStation repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the WeatherStation design in my own project?
Yes, under the terms of its MIT license, which aleksul chose for the repository.
Can I test firmware for the WeatherStation without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
