WeatherStation: common questions

What microcontroller does the WeatherStation use?

The WeatherStation is built around the ESP32-WROOM-32 or ESP32S_no_paste, from the ESP32 family.

How big is the WeatherStation PCB?

The WeatherStation measures 67 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WeatherStation?

64 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the WeatherStation design files?

From the ErikMiyoshi/WeatherStation repository on GitHub, which has the KiCad layout and the schematic; 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 ErikMiyoshi 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 ESP32 firmware against it before you order a PCB.
