ESP32 Dev V1.0: common questions

What microcontroller does the ESP32 Dev V1.0 use?

The ESP32 Dev V1.0 is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the ESP32 Dev V1.0 PCB?

The ESP32 Dev V1.0 measures 100 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 Dev V1.0?

102 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 Dev V1.0 design files?

From the EmersonEE/My_KiCad 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 Dev V1.0 design in my own project?

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

Can I test firmware for the ESP32 Dev V1.0 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.
