10/100 Mbps Ethernet
The ConnectCore 6UL SBC Pro provides two 10Base-T/100Base-Tx Ethernet interfaces using two
Microchip LAN8720Ai 10/100 Ethernet PHYs. The Ethernet PHYs are connected to the i.MX6UL ENET1
and ENET2 instances, respectively. Both Ethernet interfaces are accessible through RJ-45 connectors
with integrated link/activity LEDs. The following table shows the pinout of both RJ45 connectors.

The 10/100 Ethernet PHYs have two outputs to indicate the link and activity status of the port. These
outputs are connected to two LEDs that are integrated with the Ethernet connectors. The following
