A203 (Version 2) Carrier Board for Jetson Nano/Xavier NX/TX2 NX with compact size and rich ports (Wifi, Bluetooth, SSD supported etc.)


Jetson A203 V2 is an upgraded version of Jetson-A203, which is still an extended carrier board specifically for NVIDIA Jetson Nano / Xavier NX/TX2 NX. The rich peripheral interfaces make it suitable for end-to-end AI robot applications in manufacturing, logistics, retail, agriculture, and other industries. With the powerful NVIDIA controlling module(not included) and its compact design, it is good for Video Analysis and Robotics like UAVs, Unmanned boat, Unmanned submarines, etc.

  • Compact size (87mm*52mm*26mm) saves precious space
  • Lightweight (100g) good for small AI or IoT Application
  • Compact & all-in-one design
  • Equipped with an anti-fall aviation plug that supports high currents
  • Cost-effective, suitable for narrow and small operation environment
  • Additional USB 3.0 ZIF connector compared to its original version(A203)
  • Certificate: FCC CE RoHS


A203 Version 2 is an updated version of A203. It adds additional pins and one USB 3.0 20-pin ZIF Connector. It is a high-performance, interface rich NVIDIA Jetson Nano / Xavier NX/TX2 NX compatible carrier board, providing HDMI 2.0, Gigabit Ethernet, USB3.0, M.2 key E Wifi / BT, M.2 key M solid-state drive, CSI camera, RS232, SD card, CAN, PIO, I2C, I2S, fan and other rich peripheral interfaces are suitable for environments with strict environmental requirements, small size and powerful functions.

Basically, it works with an NVIDIA  module mentioned above to achieve graphic AI applications. To be more specific, with the NVIDIA Jetson Nan/Xavier NX / TX2 NX module assembled, it could support NVIDIA JetPack, which includes a board support package (BSP), Linux OS, NVIDIA CUDA®, cuDNN, and TensorRT™ software libraries for deep learning, computer vision, GPU computing, multimedia processing, and much more. It is suitable for small-size AI graphical applications such as smart-city IoT edge devices, Home robots, UAVs, Unmanned boats and Unmanned submarines which need to have a lightweight, low power consumption and small overall design.

Part List


1 x A203 v2 Carrier Board


1 x Power Adapter 90W 19V (power cable not included)


1x Exchange line (XT30 female to DC Power Jack male)


  • The carrier board is specially designed for working with Jetson Nano/Xavier NX / TX2 NX modules and we will not include them inside.

  • When using Jetson Nano, the M.2 KEY E cannot work but instead, M.2 KEY M could. 

  • When using Jetson Nano, 'CAN' cannot work.

  • If want to burn OS into the module. First, enter the recovery mode, find the 14 pins IO on A203 V2, and connect Pin 3(RECOVERY) to GND with a jumper line.

  • We will not include a power cord, please choose a suitable form according to your country.

  1. Product Quality
    from order view
    very good base board works well for what i need, only downside is needs adequate cooling due to it being small.
