Robotics RB5 Development Kit Hardware User Manual

3.8.1 USB-Host ports

The QRB5165 processor includes two USB channels:

 USB0 (section1.2.1 #5) is for USB Type C.

 USB1 (through a USB HUB to section1.2.1 #1&#3) is USB host only ports.

RB5 supports below USB host ports by USB HUB mentioned above:

 Two Type A USB Host 3.0 (super-speed) connector, each with current limit 1.2A.

 USB 3.0 signals are also routed to high-speed expansion connector HS1&HS2.

3.8.2 USB TypeC port

RB5 implements a USB Type C port (section1.2.1#5)

This Type C port supports both device and host mode with different peripherals. The

board can work in one mode at a time.

NOTE: There is a micro USB port section1.2.2#21. This micro B USB port is used only for

debug-log-output from the QRB5165 with a debug UART to USB bridge.

3.9 Audio

The 96Boards specifications calls for a minimum of single channel audio through two

interfaces, BT and HDMI/MHL/DisplayPort.

RB5 meets this requirement with HDMI, Display Port, and other audio channels.

Note that MHL is not supported.

3.9.1 BT Audio

The BT 5.1 implementation (including audio) on the Qualcomm® Robotics RB5

Development Kit is with QRB5165 and QCA6391.

3.9.2 HDMI Audio

A 4-bit (audio out only) I2S channel is routed directly from the QRB5165 SoC I2S interface

pins to the DSI-HDMI bridge.

3.9.3 DisplayPort Audio

The DisplayPort audio is routed directly from the QRB5165 SoC eDP interface pins to the

Type C USB connector.
