## Description

Note

- The carrier board is specially designed for working with Jetson Nano/Xavier NX module and we will not include NVIDIA Jetson nano / Xavier NX inside.
- When using Jetson Nano, the wifi module cannot work with SSD together.

**Features**

- Compact size (87mm\*52mm\*26mm) saves precious space
- Light weight (57g) good for small AI or IoT Application
- Rich ports, compatible with a large number of AI schemes
- Supporting SSD
- Supporting 4G communication
- WiFi Bluetooth Supported

A203 is a high-performance, interface rich NVIDIA Jetson Nano / Xavier NX compatible carrier board, providing hdmi2.0, Gigabit Ethernet, USB3.0, USB 2.0 (w / OTG function) m.2 key ewifi / BT, m.2 key m solid-state drive, CSI camera, RS232, SD card, can, PIO, I2C, I2S fans and other rich peripheral interfaces are suitable for environments with strict environmental requirements, small size and powerful functions.

Basically, it only works with an NVIDIA Jetson Nano or an NVIDIA Xavier NX module to achieve graphic AI applications. To be more specific, with the NVIDIA Jetson Nan/Xavier 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, unmanned submarine which need to have a light weight, low power consumption and small overall design.

**Application**

- Industrial Automation
- Smart Office
- Smart City
- Smart Agriculture
- Healthcare
