## Article

W5500 Ethernet with POE Mainboard is an Arduino main control board that is highly integrated and conforms to IEEE 802.3af industry standard POE power supply protocol. The product size is the same as that of Leonardo. The onboard POE power supply voltage regulator circuit, external power supply voltage regulator circuit, SD card circuit and Leonardo main control unit circuit lead to Arduino standard interface.The main control board is designed with 4 layers of wiring and compact component layout, which greatly reduces the space waste caused by the stackable design of Shield+Arduino motherboard in the past. The small size can create more imagination space for you.
