About the Weather station PCB

Weather station is an open source AVR/Arduino PCB design by z0b1, published on GitHub. It is a 4-layer board measuring 37.3 × 36.5 mm, with 11 components from 11 distinct parts.

Its main chip is the Arduino_Nano_Every, from the AVR/Arduino family. Other key parts include the MAX485E, BME280, SDLA12TA and DS18B20. By type, the board carries 4 ICs, 3 connectors, 2 resistors, 1 module and 1 capacitor.

It belongs with the sensors, rf & radio and power & battery designs in this gallery.

From the project

I'm presenting my project of a Field Weather Station containing anemometers and wind direction sensors, also ambient temp. and humidity sensors with a UHF transmitter in the field and an at home reciever. This also includes an RPi4 B that is recieving satellite images and displaying them in a mobile phone app.

NOTE: Significant cost savings vs previous design by removing RPi + RTL-SDR setup

Weather station: common questions

What microcontroller does the Weather station use?

The Weather station is built around the Arduino_Nano_Every, from the AVR/Arduino family.

How big is the Weather station PCB?

The Weather station measures 37.3 × 36.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Weather station?

11 components, from 11 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 z0b1/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?

The repository has no license, so all rights stay with z0b1. 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 AVR/Arduino firmware against it before you order a PCB.
