//////////////////////////////////////////////////////////////////////////////////////////////////
Automatic Weather Stations (AWS) play a critical role in environmental monitoring, yet their deployment in remote and energy-constrained locations remains limited by rigid and monolithic power architectures. Conventional systems are often designed for single energy sources, leading to inefficiencies, frequent power interruptions, high maintenance costs, and poor adaptability to dynamic environmental conditions. This research proposes the development of a modular and adaptive power electronics…

AWS PROJECT: common questions
What microcontroller does the AWS PROJECT use?
The AWS PROJECT is built around the ESP32-WROOM-32E__4MB_HIGH_TEMP_, from the ESP32 family.
How big is the AWS PROJECT PCB?
The AWS PROJECT measures 206.3 × 91.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the AWS PROJECT?
207 components, from 87 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 AWS PROJECT design files?
From the marydovika/AWS 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 AWS PROJECT design in my own project?
The repository has no license, so all rights stay with marydovika. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the AWS PROJECT 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.
