## Restrictions

Restrictions apply to this equipment as it uses button/coin cell batteries:

- The equipment is intended to be used in trades, professions or industries
- The equipment is not intended for sale to the general public
- The equipment is not intended to be used where children are present
- You are aware that this equipment may not meet child safety testing requirements as it is not intended to be used by consumers or general public, but rather, is intended to be used in trades, professions or industries in conjunction with the limitations and restrictions listed above
- You are aware that these restrictions are due to a change in [A](https://www.accc.gov.au/media-release/businesses-on-notice-as-mandatory-button-battery-laws-commence)[ustralian legislation in 2022](https://www.accc.gov.au/media-release/businesses-on-notice-as-mandatory-button-battery-laws-commence) for button/coin cell batteries

A declaration of use will need to be submitted during checkout.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS114110047:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SS114110047:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## 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
- Robotics
