Arduino Serial ethernet module?

[josephchrzempiec]

Hello, I'm looking figure out if arduino supports the serial to ethernet module. I know I can use a normal ethernet shield or module like the wiznet 5100 up to the wiznet 5500. I have seen a few for the Esp32 and another STM32 micro processor. I know of the LAN8720A and that needs to be on a esp32. I have seen people asking if it can be on other arduino boards and the short answer is no. But is there a reason why it can not work on a 32bit micro processor such as the pico or arduino zero board?

The main question is why would I use one when I can get a wiznet or a ENC ethernet module. The short answer is To free up pins or to try something different. I really don't have a good answer but I would like to figure out why it will not work.

Sure it can work. No questions.

In short, if you try some thing like Telnet it works fine, so just remove the Telnet overheads, point it at a serial object and go for it.

I’d strongly suggest using a hardware UART than software serial, but no problems at all.
I’ve used a UNO to remote a 115200 serial,port wifi it thinking twice.

If needed you can implement all your serial handshake pins if needed, that’s just extra code.

Enjoy!
