I´ve just read this kit doesn´t support ethernet.

The F3 doesn't have an ethernet controller, but this wouldn't preclude using a shield with a Wiz or Microchip Ethernet via SPI

Consider using a Nucleo144 with Ethernet.

Hi Bonnes and Clive1,

Thanks. After this post, I´ve searched (link https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html) and see other kits that have ethernet support. I think with the kit NUCLEO-H743ZI2 (STM32H743ZIT6U) I´ll be able to construct a prototype to send UDP message, like socket in c, over internet.

Do you have a hint to me? I need a kit to read the three phase voltage anc current of a grid and send the arrays (of variable length) to a remote PC using some protocol like c socket. I´ll be greatefull about any hint.

Best regards,

Geraldo.

Reconsider the H7. H7 is much more complex. F7 or even F4 might be ennough. If you need good ADC behaviour, read also the Application notes regarding ADC and F2/4/7/H7. Special considerations may be needed for good resolution.
