Aetina has launched the first carrier board we have seen for Nvidia’s Jetson Xavier NX module that provides 3x M.2 expansion slots. Certified for Microsoft Azure IoT, the AN810-XNX is designed for robotics, drones, UAVs, industrial inspection, medical imaging, and deep learning applications. (See farther below for a recap of the Linux-powered Xavier NX.)

The AN810-XNX follows earlier Aetina Jetson carriers such as the Jetson Nano based, 87.4 x 67.4 mm AN110. Although the AN110 is billed as supporting both the Nano and the NX, in June of this year, Aetina released an NX-specific variant called the AN110-XNX that appears to be identical to the AN110 except for its narrower -20 to 55℃ operating range.

The 120 x 120mm, Nano-ITX form-factor AN810-XNX competes with Xavier NX carriers from D3, Diamond, and CTI that were unveiled earlier this year plus several carriers from Auvidea that launched a few weeks ago. There is also Nvidia’s $399 Jetson Xavier NX Developer Kit.
The AN810-XNX builds on the Xavier NX module’s 8GB LPDDR4 and 16GB eMMC 5.1 with a microSD slot. Further storage is available via the M.2 M-key 2280 slot (PCIe x4/SATA), which supports Innodisk’s InnoAGE out-of-band remote management SSD M.2 card. There are also M.2 E-key 2230 (USB 2.0/PCIe x1) and M.2 B-key 3050 (USB 3.1) slots and a SIM card slot.

Major ports include HDMI, GbE, 2x USB 3.2 Gen1, and a micro-USB 2.0 OTG port. Aetina does not detail the capabilities of its 120-pin MIPI-CSI-2 interface, but it would appear to be at least as capable as the AN110-XNX’s 15-pin 2-lane and 36-pin 4-lane CSI-2 interfaces.
Onboard I/Os include 2x UART, 5x GPIO, 3x I2C, and single SPI, CAN, front panel, and power/reset headers. There is also a header for the 12-19V DC input. The -20 to 70℃ operating range falls in the middle of the NX carriers we’ve seen so far. A fan with heatsink is optional.
Jetson Xavier NX recap
The Jetson Xavier NX module has a more powerful CPU and GPU than the 87 x 50mm Jetson TX2 while shrinking to the 70 x 45mm size of the Jetson Nano. The Xavier NX runs Ubuntu Linux on 6x ARMv8.2 Carmel CPU cores and provides graphics and AI processing on its 384-core Volta GPU, compared to the 512-core Volta GPU on the Jetson AGX Xavier.
The Xavier NX can run at a low of 10W — twice the minimum power consumption of the Nano. At that level, it can deliver 14 TOPS neural processing power, rising to 21 TOPS at 15W. By comparison, the larger, octa-core AGX Xavier runs at up to 30 TOPS. The Xavier NX has twice the RAM of the Nano with 8GB LPDDR4 and similarly supplies 16GB eMMC.
