Esp32 weather station: common questions

What microcontroller does the Esp32 weather station use?

The Esp32 weather station is built around the ESP32-S2-WROVER-I, from the ESP32 family.

How big is the Esp32 weather station PCB?

The Esp32 weather station measures 75.5 × 59 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 weather station?

31 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32 weather station design files?

From the mantisea12/esp32_weather_station repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32 weather station design in my own project?

The repository has no license, so all rights stay with mantisea12. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32 weather station 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.
