Board Assembly

Always make sure everything is completely powered off and disconnected from any power source before making changes to the board. Doing so while the board — or other parts of it — are still powered can cause irreversible damage to the hardware equipment!

The Nitrogen95 SMARC module, featuring on-board Wi-Fi 6 and Bluetooth 5.4, comes fully assembled with the Universal SMARC Carrier Board, heatsink, 7" touchscreen display, enclosure, desktop stand, and all necessary mounting hardware / screws / accessories — ready to use straight out of the box. The complete setup weighs 1.69 kg in total. The display connects to the motherboard via the MIPI-DSI interface (DSI0) using a 33-pin FPC/FFC ribbon cable, with the heatsink pre-attached to the module. By default, the antenna is glued to the stand for convenience and stability.

You can adjust the screen tilt vertically, like a laptop, to match your setup and preferences. If wireless connectivity is required, make sure the antenna is securely connected to U9 and the MHF4L connector on the PCB of the Sona NX611 module. We do not recommend removing the heatsink, but if necessary, it can be done using a 3 mm hex socket bit.

(Optional) If you purchased the camera version of the Nitrogen95 Evaluation Kit, connect the 15 cm 22-pin FPC cable to the J11 (CSI0) port on the Universal SMARC Carrier Board, ensuring that the side labeled "To Board" is facing upward — just like the display. The connection on the camera side should already be pre-assembled. Next, attach the 2-pin jumper wire (GND/5V) between the Universal SMARC Carrier Board J28 pin header and the camera module. When finished, compare your setup with the following to make sure it matches: https://docs.arducam.com/Ezurio-Camera/MIPI-xISP-Camera-for-Ezurio/#hardware-connection🔗.

The 15 cm 22-pin FPC cable may appear copper-colored instead of black — depending on the production batch.

First Boot

The system ships with the Yocto Walnascar 6.16.0.27 Weston release pre-installed on the eMMC (as of the time of writing). The example below shows the output from the bootlog. You can use this as a reference to verify or compare the output from your own board.

First Boot Hardware Configuration

Coming soon: EZ BSP User Guide

“Hello World”

Once the Universal SMARC Carrier Board is powered through J17using the DC barrel jack and the included power supply, the touchscreen display will initialize automatically. A green power indicator LED (D9) will illuminate; however, it may not be visible if the screen is folded down.Within a few seconds, the screen will display our Ezurio "IO" boot / loading animation. The system typically completes the boot process in under 20 seconds, after which the Weston desktop with an Ezurio logo as the background will appear. wayland-screenshot-2026-06-10_19-01-13-20260610-190148.png

Terminal and Debug Access

Cortex-A (CPU)

To set up and establish a serial connection, use the console cable provided in the kit. Connect the DB9 connector to the 6-pin Molex 53398-0671 header on the Universal SMARC Carrier Board (J18, SERIAL) — you may need to gently lift the screen for better access — and attach other end labeled CONSOLE to your host PC through an 5V USB-to-Serial adapter (not included by default); in our example, we used the Tripp Lite USA-19HS (Keyspan): https://tripplite.eaton.com/keyspan-high-speed-usb-to-serial-adapter~USA19HS🔗.Windows users can choose from terminal applications such as TeraTerm🔗, RealTerm🔗, or PuTTY🔗, while Linux users should use tools like screen, minicom or picocom. The default serial settings are 115200 baud, 8 data bits, no parity, and 1 stop bit — commonly referred to as 8N1@115200. Once everything is in place, press the RESET button (SW1), and you should see the system boot logs appear in your terminal window.

The RS232 communication requires and operates at 5V TTL levels, not standard ±12V. If you prefer working with fastboot instead, then you may also want to connect a USB-C cable to J25 and your PC. In this context, please note that powering the entire board and setup through the USB-C connection is not sufficient, as it exceeds the current limits of a standard USB port.

Remote Network Login via SSH and Ethernet 1 /2

To connect the Nitrogen95 SMARC EVK to your local or public network, plug an RJ45 Ethernet cable into either J31 or J32 on the Universal SMARC Carrier Board. 100/1000 Mbps connections are supported on these two ports; 10 Gbps not. An SSH server (Dropbear) is enabled by default and listens on port 22 for incoming connections in the background. It becomes active once the system has fully booted.Ensure that a DHCP Server is running on your network. By default, the EVK operates as a DHCP Client, automatically requesting and receiving IPv4 + IPv6 addresses through NetworkManager once available, as shown in the ip example below:

Demo Images for the Nitrogen95 EVK

UI Frameworks Demo from the KDAB Group

Ezurio has partnered with the KDAB Group (www.kdab.com), a globally recognized provider for software consulting, development, and training, specializing in embedded devices and complex cross-platform desktop applications, to provide a demo image for the Nitrogen95 EVK which showcases a number of UI frameworks suitable for use on embedded platforms like the Nitrogen95.

This image binary can be downloaded here: UI Frameworks Demo for the Nitrogen95 EVK

NOTE: After flashing the image, you will need to perform the First Boot Hardware Configuration steps as detailed above.

Additional Features & Information

Wi-Fi and Bluetooth / BLE Usage

To explore additional features and learn how to set up, bring up and use the internal Wi-Fi and BLE radio of the Sona NX611 module, for example, see https://www.ezurio.com/support/series/sona-nx611🔗.

Camera Usage

Using set-mode, select connected camera overlay for your camera of your choice
To display image from the camera on the screen use camera-display.sh script

J1 is the reserved JTAG connector, marked as DND (not fitted by default) on the Nitrogen95 SMARC module. You can populate it manually, if needed. For detailed pinout information and a list of compatible parts, refer to the SMARC 2.1 Hardware Specification, section 3.24, page 65: https://sget.org/wp-content/uploads/2020/03/SMARC_V21-specification.pdf🔗. The JTAG I/O voltage and interface operate at 1.8 V.
