The board includes a microSD card holder and has a working voltage of 5V. It

also requires an Arduino to use - either Uno or Mega - to use. To learn more

about this ethernet shield, check out the Seeedstudio Wiki.

We recommend the original Ethernet library, it now comes with W5500-chip

support! Some examples may try to initialize the SD card after the Ethernet chip,

we recommend doing it in opposite order - get the SD card initialized first

(some cards seem to care about this)

Note this product does not have PoE support, but you can add it by the addition

of a PoE splitter. We have a version that provides 5V at 2.4 Amp max into a

micro USB connector just check that your Arduino-compatible can be powered

over a micro USB connection!
