The newest addition to NexAIoT's fanless systems for factories and production lines is so versatile that, with its appearance, you might be convinced that it can even toast bread! The TT Series kicks off with the 300 model and two variants, with (TT300-F31) or without (TT300-F01) expansion extender. Choosing the extender means that you have numerous expansion capabilities at your fingertips, including a graphics card for advanced AI and predictive maintenance uses. With or without the extension, the TT 300 is an all-around fanless computer that supports an extensive range of 6th, 7th, 8th, and 9th Intel® CPUs, giving you the flexibility to adapt to both older Windows 7 and newer Windows 10 operating systems, rather than completely overhauling your ecosystem. The onboard M.2 slots are perfect for storage or communication, while the TT 300’s lightweight but sturdy design ensures that it’s the winning choice for industrial environments.
