NXP NavQ95 Vehicle Computer

Welcome to the documentation for the NavQ95, a vehicle computer reference design designed around the NXP i.MX95 developed by NXP Mobile Robotics. Please note that this board is currently a Proof of Concept only and is considered not supported by NXP.

The NavQ95 features a single main board with a small form factor and is designed to merge a Vehicle Management Unit and a Vehicle Companion Computer into one unified, heterogeneous MCU/MPU device.

Core Architecture & AI

The heterogeneous vehicle computer is powered by the NXP i.MX 95 processor and is divided into specific execution domains:

• Compute: 6x Arm Cortex-A55 cores dedicated to executing compute-intense functions.
• Real-Time Control: 1x Arm Cortex-M7 core to execute real-time control tasks.
• System Management: 1x Arm Cortex-M33 core to execute the NXP System Manager.

AI Capabilities:

• Equipped with an on-chip NXP Neutron NPU.
• High-bandwidth M.2 PCIe interfaces target up to 2 NXP Kinara Ara240 NPUs.
• Supports cloud-based AI via Wifi6 or 5G connectivity

Software Stack:

The board is designed to run open-source software, leveraging its multi-core architecture:

• Cortex-A55 Cores: Runs the Ubuntu PoC image 24.04 with ROS2 Jazzy.

Note

This is an open Proof of Concept (POC) design and is not officially supported by NXP. The design is enabled with a Vanilla Ubuntu POC layered on top of existing NXP Yocto build. This means ROS2 main installs via apt install ros2.

The unsupported software repo can be found here: https://github.com/NXP-Robotics/imx-manifest-navq95

• Cortex-M7 Core: Runs either Zephyr / CogniPilot or NuttX / PX4.
• Communication: High-speed inter-core communication is facilitated using shared memory / OpenAMP RpMsg.

Cortex-M7 realtime software

A range of software platforms can be deployed on the Cortex-M7 core. The following software platforms have been prepared for use with the MR‑NAVQ95:

• Zephyr
  • https://www.zephyrproject.org/
  • https://github.com/CogniPilot/zephyr_boards/
• CogniPilot Cerebri (Zephyr based)
  • https://CogniPilot.org/
• NuttX
  • https://NuttX.apache.org/
  • https://NuttX.apache.org/docs/latest/platforms/arm/imx9/boards/mr-navq95b/index.html
• PX4 Autopilot (NuttX based)

Hardware Specifications

Power and Memory

• Input Power: Supports an operating voltage range of 9V to 52V, with a maximum limit of 60V. This easily accommodates 3S to 12S battery configurations, delivering 60W across the 9-20V (3-7S) range, and stepping up to 125W for the 20-52V (8-12S) range.
• RAM: Up to 16 GB of LPDDR5 memory.
• Storage Options: 64 GB onboard eMMC, an Octal-SPI Flash module, a Micro SD card reader, and PCIe M.2 support for solid-state drives.

Connectivity

• Standard Ethernet: One Gigabit RJ45 port supporting Precision Time Protocol (PTP).
• Automotive Ethernet: Both 100BASE-T1 and 1000BASE-T1 ports, also featuring PTP.

Tip

100(0)BASE-T1 is Ethernet over single unshielded twisted pair

• Wireless Comms: Powered by the NXP IW612 chip for Wi-Fi, Bluetooth, and Matter support.
• Cellular Data: Includes a SIM slot and an M.2 PCIe interface meant for a cellular modem.

Onboard Mobile Robotics Sensors

• TDK ICM-45686 Inertial Measurement Unit (IMU)
• Bosch BMM350 Magnetometer
• Bosch BMP581 Barometer

Physical Interfaces

• USB 2.0 and 3.0 ports.
• Two PCIe M.2 slots (Type M and Type B).
• A 10-pin JTAG SWD debugging header.

Main Board Schematics

The MR-NAVQ95 Main Board serves as the central processing and power distribution hub for the platform. It handles the core i.MX95 compute, wide-input power delivery, and routing to all board-to-board and high-speed interfaces.

For detailed component layouts, pin configurations, and electrical routing, refer to the core system schematics:

• MR-NAVQ95-V2

Expansion Capabilities

Building upon this core Main Board, the system is highly adaptable thanks to support for modular add-on boards:
