NVIDIA introduces lower cost Jetson TX2 NX SO-DIMM module

NVIDIA Jetson AI modules and developer kits range from the entry-level Jetson Nano module (5W, ~0.5 TOPS) to the high-end Jetson Xavier AGX module (30W, 32 TOPS). The higher-end modules usually come with a 400-pin board-to-board, while cheaper/cost-down modules like Jetson Nano and Jetson Xavier NX feature a 260-pin SO-DIMM connector and small form factor.

But so far all Jetson TX2 modules came with a 400-pin connector, but this has changed with the introduction of the Jetson TX2 NX SO-DIMM system-on-module that is offered as a cost-down version of Jetson TX2 4GB module.

Jetson TX2 NX SO-DIMM ModuleNVIDIA Jetson TX2 NX specifications with highlights in bold or strikethrough showing the difference against Jetson TX2 4GB:

  • Processor – Dual-Core NVIDIA Denver 2 64-Bit CPU and Quad-Core Arm Cortex-A57 MPCore processor @ up to 2.0 GHz
  • GPU – 256-core NVIDIA Pascal GPU @ up to 1.3 GHz
  • AI Performance – 1.33 TFLOPS
  • Video
    • Encode
      • H.265 – 1x 4Kp60, 3x 4Kp30, 4x 1080p60, 8x 1080p30
      • H.264 – 1x 4Kp60, 3x 4Kp30, 7x 1080p60, 14x 1080p30
    • Decode
      • H.265/H.264 – 2x 4Kp60, 4x 4Kp30, 7x 1080p60, 14x 1080p30
  • System Memory – 4 GB 128-bit LPDDR4 51.2GB/s
  • Storage – 16 GB eMMC 5.1
  • 260-pin SO-DIMM edge connector
    • Display I/F
      • 2x multi-mode DP 1.2/eDP 1.4/HDMI 2.0
      • 2 x4 1 x2 DSI (1.5Gbps/lane)
    • Camera I/F
      • Up to 6x 5x cameras (12 via virtual channels)
      • 12 lanes MIPI CSI-2
      • D-PHY 1.1 1.2 up to 30 Gbps
    • Networking – Gigabit Ethernet
    • PCIe – 1×1 + 1 x4 1 x2  PCIe Gen2 , or 1 x1 + 1 x1 + 1 x2
    • USB – 1x USB 3.1 (5Gbps), 3x USB 2.0
    • Other I/Os – 1x SDIO, 2x SPI, 3x UART, 4x I2S, 4x I2C, 1x CAN, GPIOs
  • Supply Voltage – 5V
  • Power Modes – 7.5 or 15W
  • Dimensions – 69.6 mm x 45 mm

The main differences are the form factor, and fewer interfaces for display, camera, and PCIe. NVIDIA  Jetson TM TX2 NX places itself right between Jetson Nano and Jetson Xavier NX in terms of performance, and shares form-factor and pin compatibility with the two modules.

Jetson SoftwareNVIDIA explains the new module is suitable for mass-market AI products, and retains software compatibility with the JetPack SDK including libraries and samples for accelerators embedded into the chip. Major AI frameworks such as Tensorflow and Caffe are supported, and the company provides pre-trained AI models from NVIDIA NGC and the NVIDIA Transfer Learning Toolkit can help with quickly developing AI applications. You can download documentation and software by registering for a free developer account.

Samples of Jetson TX2 NX modules are available now for $200 on Arrow or 140 Euros on Silicon Highway Direct. [Update: It’s also listed on Seeed Studio with Jetson Mate carrier board as an option. Further details may be found on the Jetson product page.
