ESP32 2: common questions

What microcontroller does the ESP32 2 use?

The ESP32 2 is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ESP32 2 PCB?

The ESP32 2 measures 26.8 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 2?

49 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 2 design files?

From the Rugved2004/ESP32_2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32 2 design in my own project?

The repository has no license, so all rights stay with Rugved2004. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32 2 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.
