Desktop-Weather-Station: common questions

What microcontroller does the Desktop-Weather-Station use?

The Desktop-Weather-Station is built around the AO3401A, from the ESP32 family.

How big is the Desktop-Weather-Station PCB?

The Desktop-Weather-Station measures 105 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Desktop-Weather-Station?

58 components, from 33 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 Desktop-Weather-Station design files?

From the jobitjoseph/Desktop-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 Desktop-Weather-Station design in my own project?

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

Can I test firmware for the Desktop-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.
