→The hardware platform
[[File:TBDMISC-TN-002-BD.png|center|thumb|center|600px|captionSimplified block diagram of the hardware platform]]
It was designed around the system-on-module, indicated as SOM in the picture. As stated before, the range of the SOMs fitting this application is considerable. It embraces both the compact [[:Category:AXEL_ULite|AXEL ULite]] class of products and the more powerful [[:Category:AxelLite|AxelLite]] class.
Thanks to the substantial '''pinout and form factor compatibility''', the hardware design team managed to conceive a '''"one-size-fits-all" solution'''. In other words, '''a single carrier board able to host all the selected SOMs was designed'''.
Several factors differentiate the final products which are the result of different carrier board/SOM/application software combinations. Clear examples of these factors are the size and the resolution of the supported LCD screens screen which range from 7" @ 800x480 to 15.6" @ 1920x1080.
==The unified software development environment==
*[[Axel_Embedded_Linux_Kit_(XELK)|Axel Embedded Linux Kit (XELK)]].
We managed to set up in one MVM all the tools required to handle the board support packages (BSP) for all the models and to develop the main user application–which application which is based on the well-known [https://www.qt.io/ Qt 5.9.2 libraries]–in '''one''' MVM. In combination with the [[ConfigID_and_UniqueID|ConfigID]] feature, this allows the software development team to maintain '''just one application that can run on all the platform variants'''.
