Ethernet with POE IOT Board

SKU: DFR0342

The W5500 Ethernet with POE IOT Board is a new DFRobot Ethernet family member. Based on ATmega32u4 and W5500 chips, it matches Arduino Leonardo’s footprint, compatible with most Arduino shields/sensors for IoT apps. Unlike W5200 shield, it integrates POE (IEEE 802.3af) and WOL mode. Its 4-layer design solves stackable space waste, plus a professional PD chip ensures power reliability in complex environments.
