Weather station: common questions

What microcontroller does the Weather station use?

The Weather station is built around the ESP32-S3-WROOM-1-N4R2, from the ESP32 family.

How big is the Weather station PCB?

The Weather station measures 84.8 × 67 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Weather station?

77 components, from 40 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 Weather station design files?

From the benjisu03/weather-station-pcb 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 Weather station design in my own project?

The repository has no license, so all rights stay with benjisu03. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 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.
