ESP-32-Dev-Board: common questions

What microcontroller does the ESP-32-Dev-Board use?

The ESP-32-Dev-Board is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ESP-32-Dev-Board?

The ESP-32-Dev-Board measures 25.4 × 62.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP-32-Dev-Board?

27 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP-32-Dev-Board design files?

From the Fred98246/ESP-32-Dev-Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP-32-Dev-Board design in my own project?

Yes, under the terms of its MIT license, which Fred98246 chose for the repository.

Can I test firmware for the ESP-32-Dev-Board 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.
