The KiCad project lives in the AronASzucs/ESP32-Geiger-Counter repository on GitHub; these links point at the commit this page was built from.

ESP32-Geiger-Counter: common questions

What microcontroller does the ESP32-Geiger-Counter use?

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

How many components are on the ESP32-Geiger-Counter?

70 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-Geiger-Counter design files?

From the AronASzucs/ESP32-Geiger-Counter repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the ESP32-Geiger-Counter design in my own project?

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

Can I test firmware for the ESP32-Geiger-Counter 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.
