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 UAV, Unmanned boat, Unmanned submarine, etc.

  • 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 Wifi module cannot work with SSD together.

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

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

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


  • Compact size (87mm*52mm*26mm) saves precious space
  • Light weight (100g) good for small AI or IoT Application
  • Rich ports, compatible with a large number of AI schemes
  • Supporting M.2 key M SSD
  • Micro SD card slot
  • WiFi Bluetooth Supported
  • Supporting RTC 
  • Supporting USB 3.0 ZIF connector


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 application such as smart-city IoT edge devices, NVR, Home robots, UAV, Unmanned boat and Unmanned submarine which need to have a light weight, low power consumption and small overall design.
