WIZnet Surf 5 Microcontroller Evaluation Board

WIZnet Surf 5 Microcontroller Evaluation Board is based on the W7500 MCU that can be used with PoE modules. The Surf 5 includes a built-in RJ45, LDO, and UART to USB with the W7500 microcontroller. The WIZnet Surf 5 power consumption depends on how much users use the peripheral in what temperature environment.
