PoE Shield

The PoE Shield gives OpenMV Cams with on-board Ethernet a single-cable IP-camera deployment by delivering both power and network over 802.3af PoE. Use it when 100 Mb/s is enough; reach for the Gigabit PoE Shield when you need more bandwidth.

Usage

When the shield is connected to a PoE switch, the camera’s 10/100 Ethernet PHY appears as a network.LAN interface. DHCP runs automatically once the link comes up:

import network
import time

lan = network.LAN()
lan.active(True)
while not lan.isconnected():
    time.sleep(1)
print("Ethernet IP:", lan.ipconfig("addr4")[0])
