Windsensor: common questions

What microcontroller does the Windsensor use?

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

How big is the Windsensor PCB?

The Windsensor measures 70 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Windsensor?

123 components, from 44 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 Windsensor design files?

From the kristofkatzenberger/windsensor 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 Windsensor design in my own project?

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

Can I test firmware for the Windsensor 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.
