Am3359 development board -- gigabit network transformer manufacturer

Am335x has the following advantages:

First: the device is the cheapest cortex A8 processing chip, which is crucial to the Chinese market, and the micro single port network transformer is even the decisive factor.

Second: the most comprehensive chip in the history of Ti.

Third: the most clear product positioning, industrial control MCU

Fourth: the only MCU integrated with two Macs

Fifth: the only support for androd 4.0 at present, And supports three operating systems at the same time Linux，Android， WinCE.AM335X The development board has perfectly supported the above three operating systems. The micro gigabit network transformer has been used by many domestic manufacturers in industrial control, medical electronics, energy conservation and environmental protection, intelligent transportation, energy conservation, power system, communication system, textile industry, numerical control industry, automobile electronics, industrial touch screen control system, robot vision and media It is widely used to deal with the price of wireless applications, digital home appliances, on-board equipment, communication equipment, micro single port network transformers and other harsh environments
