DB9 Male Connector
DB9 Female Connector
UART1 is dedicated as the debug or console port. The default communication settings are
Baud Rate 115200, 8 data bits, no parity, 1 stop bit and no flow control.
Note that UART1 is at CMOS signal level. There is no RS232 transceiver on the port.
A separate debug cable is required to connect UART1 to a PC terminal.
A DB9 null modem cable (or adapter) is required when you want to connect UART1 to a
PC with terminal emulation software such as TeraTerm.

3.3 USB Connectors
The USB interfaces on NSD2105 include a USB 2.0 OTG port and four USB2.0 host ports.
Speed of up to 480 Mbps supported.
The USB 2.0 host interface is connected to a hub controller to extend host ports. Two of the
USB2.0 hub ports are available in type Aconnectors for users. The other two USB ports are
available in pin-headers reserved for WiFi module or other devices.
NOTE: The USB 2.0 OTG can be used in host mode or device mode. If you would like to
use it in host mode, a separate OTG-to-host cable is required.
The USB 2.0 host connector is a regular USB typeA connector that can be connected to
+5V USB storage device. This port is mainly used to connect to USB flash drive.
