WeatherV3-kernelcon2026: common questions

What microcontroller does the WeatherV3-kernelcon2026 use?

The WeatherV3-kernelcon2026 is built around the ESP32-WROOM-32E-H4, from the ESP32 family.

How big is the WeatherV3-kernelcon2026 PCB?

The WeatherV3-kernelcon2026 measures 66 × 143.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WeatherV3-kernelcon2026?

82 components, from 24 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 WeatherV3-kernelcon2026 design files?

From the ZonkSec/kernelcon-2026-badge 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 WeatherV3-kernelcon2026 design in my own project?

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

Can I test firmware for the WeatherV3-kernelcon2026 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.
