This Technical Note illustrates how to use the [[:Category:SBC-AXEL|SBC Axel]] (SBCX for short) to implement a Microsoft Azure-enabled edge device. Thanks to its flexibility and to its rich set of I/O interfaces, the SBCX single-board computer can be leveraged to implement an IoT gateway with good processing power. This combination makes this board particularly suited for the applications where significant computations have to be [[MISC-TN-005:_Running_AWS_Greengrass_Core_on_SBCSPG#Introduction|deployed on the edge]].

It is worth to remember that this Technical Note is not a step-by-step guide to set up the edge device and the cloud platform to implement an Azure-based system. Azure documentation is rich and detailed in this regard. Rather, this document aims to underline some specific SBCX-related steps required to run the Azure IoT Edge runtime on this device successfully. Nevertheless, in the following sections, several relevant links to the Azure documentation will be provided.
