Advantages of computer module

Computer module interface

With the development of computer industry, computer modules have been developed. There are manufacturer's standards and international standards for interfaces, both of which are available in the market.

The smallest computer module in the world

PC 104/PC 104 plus interface:

IEEE-P996. 1 and PC 104 defined by IEEE Association are industrial control buses specially defined for embedded control. The optimized small stacked embedded structure is adopted. There are two versions of PC 104, 8 bits and 16 bits, corresponding to PC and PC/AT respectively. PC 104PLUS corresponds to PCI bus and is widely used in industrial control field. More than 200 companies around the world use these open specifications to produce and sell various PC/ 104 computer modules. The processor mainly adopts low-power X86 microprocessor, and a few adopt ARM architecture.

SODIMM 200 interface:

According to the physical and electrical standards of DDR I, the signal is customized by the manufacturer, the module size is 67.6mm x 36.7mm, and the product is Toradex's ARM computer module family Colibri series. The characteristics of the module are that the main processor adopts XScale PXA processor from 208MHz to 806MHz or Nvidia multi-core processor Tegra 2/3, and the memory and storage space also have various configurations. The operating system can choose WINCE, QNX or embedded Linux, and the modules are compatible with each other.
