From the project

A production-grade weather station firmware written in Rust targeting the STM32F407VGT6 MCU. It collects environmental data from multiple sensors and transmits readings over WiFi (ATWINC1500), BLE (RN4870), LoRa, UART, MQTT, and HTTP — with optional Ethernet (W5500) and Cellular

A production-grade weather station firmware written in Rust targeting the STM32F407VGT6 MCU. It collects environmental data from multiple sensors and transmits readings over WiFi (ATWINC1500), BLE (RN4870), LoRa, UART, MQTT, and HTTP — with optional Ethernet (W5500) and Cellular (SIM7600E-H) connectivity.

Why STM32F407? Industrial temperature range for outdoor deployment, hardware FPU for sensor math, three SPI buses for concurrent LoRa/Ethernet/WiFi, dedicated UART for each communication module, and excellent Rust embedded-hal support. Single-MCU architecture simplifies firmware (one…

WeatherStation: common questions

What microcontroller does the WeatherStation use?

The WeatherStation is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the WeatherStation PCB?

The WeatherStation measures 100 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the WeatherStation?

91 components, from 73 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 WeatherStation design files?

From the ppusapati/weather 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 WeatherStation design in my own project?

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

Can I test firmware for the WeatherStation 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.
