ESP32 4 layers: common questions

What microcontroller does the ESP32 4 layers use?

The ESP32 4 layers is built around the ESP32-C3-WROOM-02-H4, from the ESP32 family.

How big is the ESP32 4 layers PCB?

The ESP32 4 layers measures 88.7 × 55.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 4 layers?

85 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 4 layers design files?

From the Chirag-Vadrali/PCB_Designs 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 4 layers design in my own project?

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

Can I test firmware for the ESP32 4 layers 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.
