+NXP ADTJA1101-RMII Automotive Ethernet Adapter
+##############################################
+
+Overview
+********
+
+The ADTJA1101-RMII is an automotive Ethernet adapter card specifically built to
+add 100Mbps automotive Ethernet connectivity to the S32K148 Microcontroller and
+i.MX8 platforms.
+
+This shield can be used with the NXP S32K148-Q176 evaluation board by plugging
+into the common expansion connector, through which the ADTJA1101-RMII connects
+the RMII interfaces of the S32K148 directly to NXP’s 100BASE-T1 Ethernet PHY
+TJA1101.
