About the Meteo station PCB

Meteo station is an open source ESP32 PCB design by alicjamusial, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 110 × 90 mm, with 23 components from 16 distinct parts.

Its main chip is the ESP32-WROOM, from the ESP32 family. Other key parts include the TP4056, LF33_TO220, DS18B20, BH1750 and BME280. By type, the board carries 6 ICs, 5 capacitors, 5 resistors, 2 diodes, 1 battery holder and 1 jumper.

It belongs with the power & battery, sensors and iot & wireless designs in this gallery.

From the project

Meteo station project - PCB based on ESP32.

Meteo station is my small after-hours project that contains of three repositories: - Meteo station PCB based on ESP32 (this repo) - Meteo station code - Meteo station 3D prints

As the name suggest, is a DIY self-sufficient weather measuring device. I decided to design it as a PCB board with goldpins to stick-in or stick-out individual components and sensors (ESP32, BME280 etc.) to make it more reusable. It could have - of course - been integrated on board, but it would be more expensive and time-consuming to create.

Meteo station: common questions

What microcontroller does the Meteo station use?

The Meteo station is built around the ESP32-WROOM, from the ESP32 family.

How big is the Meteo station PCB?

The Meteo station measures 110 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Meteo station?

23 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Meteo station design files?

From the alicjamusial/meteo-station-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Meteo station design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which alicjamusial chose for the repository.

Can I test firmware for the Meteo 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.
