Pinouts

The Ethernet FeatherWing plugs into any Feather and adds hard-wired networking. To make it as cross-platform

compatible as possible, we use only SPI plus one extra, configurable pin. It's not going to be gigabit (or even multi-

megabit) speeds but it will work!

Power Pins

The WIZ5500 Ethernet chip (and really any ethernet chip) are fairly high current devices, requring about 150mA

whether or not actively transmitting. The chip is powered from the 3.3V and GND pins indicated and does not have an

internal regulator.
