About the Weather station PCB

Weather station is an open source ESP32 PCB design by ismangoman, published on GitHub under the MIT license. It is a 2-layer board measuring 36 × 49.8 mm, with 14 components from 13 distinct parts.

Its main chip is the ESP32-WROOM-32E, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 9 connectors, 2 ICs, 2 resistors and 1 transistor.

It belongs with the power & battery designs in this gallery.

Weather station: common questions

What microcontroller does the Weather station use?

The Weather station is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Weather station PCB?

The Weather station measures 36 × 49.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Weather station?

14 components, from 13 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 ismangoman/Weather-station 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?

Yes, under the terms of its MIT license, which ismangoman chose for the repository.

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.
