4.4 Connectivity and Settings
4.4.1 RJ45 Ethernet Connector
The S5D9 MCU Board features standard Ethernet connector RJ45 with built-in magnetics. It is connected to RealTek
PHY interface P/N: RTL8189EM-CG. The PHY is connected to the MCU via RMII interface. The RJ45 connector is
HanRun Electronics Ltd. P/N: HR915102AE. Its front view is shown in Figure 10.
The pin mapping of the connector matches the standard for Ethernet ports. The pin mapping is shown in the following
table.

4.4.2 PMOD Connector
The S5D9 MCU board includes one PMOD connector. It can interface with modules that require UART, I
interface. The function of the PMOD is dependent on the MCU pin functions initialization. The PMOD connector pin
map is shown in the following table.
