Esp32-ethernet: common questions
What microcontroller does the Esp32-ethernet use?
The Esp32-ethernet is built around the ESP-WROOM-32, from the ESP32 family.
How big is the Esp32-ethernet PCB?
The Esp32-ethernet measures 54 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp32-ethernet?
36 components, from 23 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp32-ethernet design files?
From the russss/esp32-ethernet repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Esp32-ethernet design in my own project?
The repository has no license, so all rights stay with russss. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp32-ethernet 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.
