What Is So Special About Computer-on-Module?

To start with, it is the board's size. Its slight physical size with essentials like I/O or input or output controllers and a processor makes it a space saver in any electronic device. The system is embedded into this small board. It is like a single board tiny computer. Upgrading the CPU is very easy because of its configuration. There is no necessity to spend more money for creating a new design of carrier. In other words, money can be saved in the event of relevant CPU upgrading. COM operates using low power. This too is cost saving especially in the long run. Another benefit of not having to redesign or build another carrier is in terms of development time. Using COM means shorter development time.       

Why Should You Choose BT9A3 Series?

This particular model is classified as COM Express Mini, Type 10. It has Intel Atom E3800 Series, Intel Celeron processor and other electronic chips on it. Offering low powered output and capable of working in a broad range of temperature, this Computer-on-Module board has an embedded system in an ultra-compact design. Its physical size is merely 84mm by 55mm. The most outstanding feature is its damage free intelligence system, which gives overheat, fan speed and voltage failure alarm. It also comes with various optional features like heat sink with fan.
For those who are looking for a low powered COM Express Module that can operate effectively in a wide range of temperature, the BT9A3 Series might be the answer.
