What is The Embedded Board?

What is an embedded board? The embedded board needs to be controlled in the device and perform data processing on the embedded industrial computer CPU board.

Generally, there are requirements for the size and high power consumption of the motherboard. Generally speaking, Embedded Board has characteristics of high integration, small size, and low power consumption! Usually, a size smaller than 170*170mm belongs to the embedded board.

Features of embedded board

Small size, high integration, low power consumption, and high-temperature requirements. The characteristics of the embedded board are small size, low power consumption, strong control function, flexible expansion, miniaturization convenient use, etc. Most such Embedded Boards are widely used in instruments and meters, measurement of physical quantities such as frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, element, pressure, etc. Realize the digitization, intelligence, and miniaturization of instruments and meters.

According to the characteristics of the embedded board, they can be classified as follows:

1. Size: Mini-ITX is a standard size, and the embedded industrial control board is 5.25 inches in size and can be equipped with half-length cards and CD-ROM size; the epic 4-inch embedded board is a general-purpose motherboard with many ports and strong expansion. A 3.5-inch motherboard is the same size as a large hard drive. The 2.5-inch model is similar in size to a laptop hard drive. Below is a 1.8-inch PicoITX motherboard. The COM-E mainboard is also called the core board, it is a high-performance mainboard and uses more medical equipment; The Q-SEVEN mainboard is an extension of the COM-E mainboard with connectors to connect the core board to the carrier board.

2. Integration: On the embedded board, more than 80% of the CPU is integrated, and most industrial computer CPUs are mainly onboard, so the memory will be more stable when onboard. port, strong expandability, slot miniPCIE, and m.2.

3. Low power consumption: Low calorie is required to store battery for a long time, mainly used in mobile devices.

4. Temperature: The temperature of the industrial computer CPU used in different industries is also different. embedded boards are generally used at 0-50°C for civilians, -10-60°C for commercial use, -27-70°C for industry, -40-85°C for military use, and -60-100°C for aviation.

5. Power supply mode: ATX power supply and DC direct current, embedded boards could be powered within the voltage range

6. Display: There is LVDS.According to the type of embedded board, it is usually divided into two categories:

1.) Risk-based ARM embedded boards and x86-based embedded boards. X86-based embedded boards (usually using INTEL, via, AMD, or other X86 chip manufacturers, such as Taiwan RDC, Taiwan ICOP, etc.); Risc-based ARM embedded boards (ARM licensed, each with their special features ). Embedded ARM boards are usually board CPUs, not necessarily x86cpu-based motherboards.

The standard system architecture of embedded systems has two major blocks, which currently dominate the so-called RISC (ReducedInstructionSetComputer, reduced instruction set computer) processor. RISC systems range from ARM, MIPS, PowerPC, ARC, and Tensilica to RISC processors. However, although these processors are also RISC systems, they differ in instruction set design and processing unit structure, so they are completely incompatible with each other. Software developed on a specific platform cannot be used directly by other hardware platforms and must be recompiled.

2.) Followed by Complex Instruction Set Computer (CISC) processor system ComplexInstructionSetComputer, we know that the Intel X86 processor belongs to the CISC system, CISC system is a very inefficient system, x86 embedded industrial computer system processing Computers are mostly old products, such as Pentium3 processors are still common in industrial computers and have been out of the PC market for many years. Since the efficiency and power consumption ratio of this generation of products can be said to be the best choice for X86 systems in the past, plus it has been proven by the market for a long time and has high stability, it is often used for applications with low-efficiency requirements but Stability requirements are high, such as industrial control equipment and other products.

Embedded Board Application

Embedded boards are small in size and powerful in performance, so such computer-embedded boards can be used in many occasions, large motherboard instruments, including medical, banking, industrial control industry, drones, intelligent robots, home entertainment, business office, and so on.
