well here it is !!

I would like to know if there is existing a library to connect the mcu to a server with socketIO.

Good one. Use flowchart to code converter in your assignment

What is that display? I couldn't find it on Seeed's site.

Azure Sphere MCUs. A new cross-over class of MCU with built-in Microsoft security technology, connectivity, and the headroom to support dynamic new experiences. The Pluton Security Subsystem creates a hardware root of trust, stores private keys, and executes complex cryptographic operations. A new crossover MCU combines the versatility and power of a Cortex-A processor with the low overhead and real-time guarantees of a Cortex-M class processor. Built-in network connectivity provides secured, reliable, online experiences and ensures devices are up to date.

I'm trying to get a handle on this device but it sounds very proprietary with a minimalist Linux kernel that handles a very thin API. The API sits between the kernel, the hardware and the user interface. It sounds as if Microsoft is using proprietary hardware with integrated firmware API that are not part of the open source Linux component. Are the drivers pre-installed in proprietary firmware as well? Are the security updates, firmware updates? The architecture also looks incredibly weak. No on-board USB without a USB to GPIO+SPI+I2C adapter interface. A micro USB power only connector. This seems like a device that only has the benefit of a thin Linux UI with a promise by MicroSoft of maintaining/updating very proprietary hardware/firmware security and API. With the exception of a promise of better security than a Raspberry pi, Beagleboard, NXP, Arduino, Parallax...I do not see the benefits at twice the cost. What am I missing? No clean integration into a Win 10 system except a promise of MicroSoft's cloud architecture. The problem there being that MicroSoft changes course every 18 months or so and your prior technology is borderline obsolete. Promises of backwards compatibility? With the exception of the surprise of integrated backwards compatibility in Win 10 MicroSoft has a long history of crippling backwards comparability while simultaneously promising backwards compatibility. Hopefully those days are gone along with the incompetence of Ballmer. It looks to be somewhere between an Arduino and a Pi with all of the limitations of an Arduino in terms of simplistic GPIO+SPI+I2C...and none of the frills of a Pi3 bluetooth, builtin USB, dedicated video GPU core plus the GPIO+SPI+I2C... Where's the upside? Promises of higher security without access to the firmware source are simply that, promises.

That is cute and all.. but all I need to know is how to flash Kali Linux to it and do the internal wifi cards support wifi injection hahaha.....

ARM cpus? Not x64? The board will die fast as there are better ARM solutions.
