PCM-4386 User Manual 2
Chapter 1 Introduction
1.1 Introduction
The PCM-4386 is a 4” SBC (Single Board Computing) with a high per-
formance and lower power based on Celeron M processors.
The PCM-4386, in conjunction with Intel 852/855 GM/GME chipset,
supports processors clocked at up to 1GHz, six USB 2.0 compatible ports,
2 PCI Fast or Gigabit Ethernet interface, 2 Channel LVDS interface, and
one MIO expansion connector, and accommodate up to 1GB of ECC
DDR RAM memory.
SpeedStep (EIST) technology is another one of the important features for
PCM-4386 which can save energy and ensure longer battery life, since it
allows the operating system to reduce the processor clock speed when
there is not much work to be done.
