Open Source ESP32 Ethernet, Wi-Fi & Serial Gateway

[selcuk]

Hello All,

I want to share a recent project of mine with you. This is a design based on ESP32 chip. It is compatible with open source esp-at project. One can easily develop a custom firmware on it as well. Schematics, layout, PCB antenna design and simulations, pin out diagram, part list and much more are available on the link below:

It is an "Open Source Hardware" developed with "Open Source Software". The software list includes but not limited to KiCAD, OpenEMS and Octave.

The board has ESP32-D0WD-V3 MCU, 16 MB serial flash memory (W25Q128JVSIQ), 10/100 Mbit Ethernet (RTL8201F), 2.4GHz PCB antenna, USB-Serial programming, monitoring and general purpose interface (CH340G), 5V to 3.3V voltage regulator (1117 series), 2.93V supply voltage supervisor (APX811-29UG), protection components and RF shield.

Kind Regards,
Selçuk
