Hi everyones,

I am searching a Ethernet breakout board for my eval board. I saw on this 

http://blog.tkjelectronics.dk/2012/08/ethernet-on-stm32f4discovery-using-external-phy/

 that he is using the 

DP83848 Phy breakout board but it seems difficult to find such a board.

Thus, I found an other one you can see it on this 

http://radiospares-fr.rs-online.com/web/p/kits-de-developpement-pour-processeurs-et-microcontroleurs/7581032/

 and characteristics seem also good.So, can you confirm me I can use this board as an ethernet module for my STM32F4Discovery board ?Thks. #stm32 #discovery #ethernet-interface

I use

 with board

 and it works good. There's some examples.

Yes but you didn't answer my question, I wanna know if  the other board can be used with STM32F4 ?

I think that it can, but there isn't examples. You will need to work with SPI

You should be able to connect it, be aware that the STM32F4-Discovery uses 3V not 3.3V. You'll need to do your own due diligence.

You'd have to find a free SPI port, and code the software, is that something you're comfortable doing? There are other board solutions for adding Ethernet to the Discovery, and a whole slew of more integrated solutions for the STM32F2/4 on eBay and the likes.

Indeed, you may be right, it would be easier to use the base board provided by ST. And with their standard library, I think I can be comfortable :)

It's kinda more expensibe but It should be the best solution to me.Thanks again for your advices clive1.
