ESP32-NAT

ESP32 NAT Router is a tiny, custom ESP32- based PCB that turns Wi-Fi into a portable NAT router. Powered by Martin Ger’s ESP32 NAT Router firmware, it enables network bridging, client isolation, and internet sharing in a fully DIY, open-hardware package.

technical_. technical_. rejected ESP32-NAT ago

Permanently rejected as you have ignored multiple instances of AI read.me flagging.

Readme is still flagged as ai generated. also bom.csv isnt loading in github as a bom.

Your README.md is still AI-generated, especially the latter part; please rewrite it. Additionally, we need your PCB source files (i.e. .kicadpro, .kicadsch, and .kicad_pcb), not just your gerbers.

Update README

Rewrote the whole README and added 3D rendered images. See the changes at https://github.com/Jaydev-1510/ESP32-NAT. There's nothing to write more about

It looks like your readme is made by ai, which we do not tolerate. Additionally, please include your pcb files in your repo!

Revised the Schematic

I was doubtful about my schematic and routing. Therefore, I revised the entire schematic. There were a few things to be resolved. Also I forgot to route 3v3 !!!! Here's the updated schematic and PCB-

Routed the PCB

The placement was quite challenging, but I managed to fit all of the PCB in 42mm. I routed all the components and chose 4 layer stackup with 1 3v3 and 1 GND plane. I hope the cost is less than $60. Here's the work done today.

Completed the USB-UART IC

I completed the USB-UART IC schematic with the help of Espressif's ESP32 devkit schematic and Robert Feranec's video. Here's the image of the work done.

Started the schematic

After a long break from blueprint I cam back to work on this project. I took reference from the Espressif's ESP32 devkit schematic and Robert Fernec's videos too. This what I have cooked for now. I will do the USB to UART later.

Initial Planning

Explored various ESP32 modules and found ESP32-WROVER-32IE-N16R8 to be interesting because it has a big flash (16MB) and PSRAM (8MB) which is good for a ESP32 based NAT router. I am planning to keep male USB-A so that i can directly plug it into adapter. Also there will be an external SMA antenna to boost the WiFi range and speed. Here is the block diagram I have prepared today-
