NavQPlus
Mobile Robotics companion computer
reference design using i.MX 8M Plus MPU
NavQPlus

ABOUT THE NavQPlus
The NavQPlus is a small purpose-built Linux computer evaluation kit (EVK)
based on the NXP i.MX 8M Plus applications processor. It is focused
on the common needs of mobile robotics systems, with a small form factor,
Dronecode-compliant JST-GH connectors, and available software stack
including Linux Desktop POC and Robot Operating System (ROS2).
It has a SOM identical to the i.MX 8M Plus EVK, with a minor exception
that the NavQPlus supports 8GB LPDDR4 while the i.MX 8M Plus
EVK SOM supports 6GB LPDDR4. The NavQPlus is an intermediate step
between the i.MX 8M Plus EVK and a fully custom board design.

1Confirm Boot
Switches
The boot switches should be set to boot
from the eMMC. SW2[1-2] are used for
boot. See table.
2Connect
Power Supply
Power on the NavQPlus by plugging
in a USB-C cable to the centermost
USB-C port (USB2). To ensure enough
power is provided, a >5W supply is
recommended. The NavQPlus will boot -
the three LEDs by the USB1 port should
all be on, as well as two LEDs next to the
CAN bus connectors.
3Connect USB
Debug Cable
Adapter to the UART2 (A53 Debug/
Console) port on the NavQPlus. Connect
the other end of the cable to a PC
acting as a host terminal. One UART
connection will appear on the PC.
If the serial port is not recognized,
download and install updated drivers.
The drivers can be found at
www.ftdichip.com/Drivers/VCP.htm
Open the serial console application
(e.g. PuTTy for Windows, Minicom on
Linux), choose the COM port number
and set the baud rate to 115200.
SETTING UP THE SYSTEM
The NavQPlus is shipped with the items listed in Table 1. Ensure the items

Login
If the boot was successful, in the terminal
it will ask for the username and then
the password. The default username/
password is as follows:
Username: user
Password: user
Congratulations, you are up and running.
Now with the NavQPlus setup
complete, you can start to install other
software packages and run your own
code. For example, ROS2 (Robot
Operating System) is commonly used
as a framework for controlling robotic
systems, with plenty of compatible
packages being available.

Please note the following FCC information.
• Contains Transmitter Module FCC ID: VPYLB1ZM or Contains FCC ID: VPYLB1ZM
• FCC CAUTION: Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
• This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference and (2) this device must accept any
interference received including interference that may cause undesired operation.
The available scientific evidence does not show that any health problems are associated with using
low power wireless devices. There is no proof, however, that these low power wireless devices are
absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the
microwave range while being used. Whereas high levels of RF can produce health effects (by heating
tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health
effects. Many studies of low-level RF exposures have not found any biological effects. Some studies
have suggested that some biological effects might occur, but such findings have not been confirmed
by additional research. LBEE5QD1ZM has been tested and found to comply with FCC radiation
exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF)
Exposure Guidelines
It is necessary to take a SAR test with your set mounting this module (except to use only Bluetooth).
Class II permissive change application is necessary using the SAR report. Please contact Murata.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment
and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment should be installed and
operated keeping the radiator at least 20 cm or more away from person’s body.
