ESP32ETH: common questions
What microcontroller does the ESP32ETH use?
The ESP32ETH is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the ESP32ETH PCB?
The ESP32ETH measures 40 × 68 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32ETH?
32 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESP32ETH design files?
From the nuclearcat/ESP32ETH repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ESP32ETH design in my own project?
Yes, under the terms of its LGPL-2.1 license, which nuclearcat chose for the repository.
Can I test firmware for the ESP32ETH 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.
