The EINDOS-PB550 is a highly complex PC/104 board with the functionalities of a embeded Module. It is equipped with a SiS552 Pentium MMX Compatible 133 to 250 MHz CPU, 32Mbytes up to 256MBytes Soldered DRAM, PCI and ISA bus,and additional peripheral devices, such as 4 serial interfaces, one printer interface, floppy, LAN, , 2 USB interfaces,keyboard/mouse, CompactFlash, CRT, TFT  and two IDE connections. Floppy:
  USB: 2 (1.1)
Parallel: Uni/ECP/EPP
Video Memory: Up to  64MB
Analog CRT:

The power supply of the hardware module is effected either over the PC104 header strip or via a power connector which is provided for the power supply.Only 5 volt ¡À 5% of voltage are necessary for the operation of this hardware module. The tensions which are additionally indicated on the power connector are not required on the hardware module. These tensions are provided through the PC104 bus for possibly existing PC104 devices. 

LCD Digital: 18 bit TFT
Serial COM1/COM2 TTL/RS232
Serial COM3/COM4 TTL/RS232/RS422/485
IrDA: 1.1
Sound: No

The CPU is integrated in the SiS552. This CPU is a x86 compatible processor. Concerning his performance category the processor is comparable to a Pentium MMX from Intel.The EINDOS-PB550 Board is delivered with hard soldered SDRAM. SDRAMs of different makes are employed. The RAMs are organised in a 16Bit wide range, a memory extension of 32MB up to 256MB is therefore possible.All timing parameters for the different makes and stages of extension are automatically set through the BIOS. It is therefore not necessary to make manual settings in the BIOS setup in this regard.

Speaker:
CompactFlash: Type II, IDE Master
Power Management: APM, ACPI
Watchdog: 1s - 255h
RTC: External/Internal  Battery
BIOS: Award (Flash)
Power Normal: 5V/1A
A compact flash holder type II is provided on the EINDOS-550 board. All commercial compact flash cards including Micro Drivers can be operated with this holder. These cards are approached in the ATA modus and they can therefore be responded like normal hard disks.The compact flash card is run as master device on the first IDE controller. If the compact flash card is stuck, only one further slave device can be run on that IDE connector. Power Suspend: 5V/300mA
Power: single 5V
   Cooling Type: Passive
Shock/Vibration: 50G/2.0G (nonperating).
