3.8. UART Interfaces (J2002/J2003)
The 5G EVB supports two UART interfaces: main UART J2002 and debug UART J2003, supporting baud
rate of 115200 bps by default.
The main UART interface is used for communication between the module and the host application.
The debug UART interface is used for Linux console and log output.
The following figure shows a block diagram of UART interfaces of the EVB.

3.9. PCIe to USB Interface (J1601)
The 5G EVB reserves a PCIe 3.0 signal over USB interface for developers’ testing, and this function is not
enabled by default. Please refer to the following block diagram.
