PoE Shield

The PoE Shield adds 802.3af Power-over-Ethernet to OpenMV Cams that have an on-board Ethernet PHY — one cable to a PoE switch carries both power and the network link.

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])
