Header Pinouts on WIZ110SR?

I notice there are 5 header pins on the top of the board. Is there a reference to these pins?

This board has a built-in RS-232 port, but I just want access to the UART TX,RX pins. Are these available on the PCB? Are they available on that 5 pin header?

Thanks…

Hello.


5 header pins are JTAG pin.
Therefore, it is difficult to use UART TX, RX pins directly.

If you are in the process of selecting products, we recommend the following products.


And I personally recommend a series of 550 or more with hardware and software resources open.

Please refer to wizwiki for products with open hardware and software documentation.

Hi.

You just want access to the UART tx,rx signal??

if so I recommend WIZ100SR. It is use same MCU and PHY with wiz110sr.

If you want use UART TX, RX in wiz110sr, you must be soldering in RS232 chip & wire.

It is not recommend. So, I wish you use wiz100sr or other modules…

Thank you
