Sensoray’s Model 301-06 is a low cost, low power CPU board featuring a combination of characteristics required in most embedded applications using the PC/104+ form factor (3.8”x3.6”)

CPU
The AMD Elan SC520 processor running at 133 MHz provides the performance approximately equivalent to that of a Pentium 75. The board is supplied with 32 MB SDRAM and 16 MB flash disk.

I/O
The 301-06 has 2 serial (RS-232) ports supporting communication speeds of up to 115 Kbps.

Expansion Buses
Model 301-06 supports both PC/104 and PC/104+ expansion buses. It allows up to 4 external PC/104+ devices.

Ethernet
A 10/100Base-T Ethernet adapter is integrated on the Model 301-06 board. It is built with Intel GD82559ER PCI Ethernet controller.  The drivers for various operating systems are available. The board is equipped with an RJ45 network connector.

Non-volatile memory
The 301-06 is supplied with a 16 MB flash disk which appears to the software as a regular hard drive.  A socket is provided for an optional DiskOnChip (a 3V part is required)

Power
Only one power supply (+5V) is required. A power connector allows connecting additional power supplies (-5V, +12V, -12V) to the expansion buses, if necessary. Total power consumption of the board is 5 W.

Watchdog Timer
An I/O mapped watchdog timer can reset the CPU or it can drive an open-collector output to reset external circuitry. The time out value is 1.6 seconds.

Accessory Modules
PC I/O board Model 300TA: PC/104, 2 IDE, 1 floppy, 1 parallel, 2 serial, keyboard, and mouse.
SVGA board Model 322: PC/104+, SVGA, TV output.

Bus Buffers
The data, address and control bus signals are buffered with 16244’s and 16245’s. This allows stacking several PC/104 boards without degrading signal quality.  This feature makes it possible to add five PC/104 peripheral boards to one 301-06 CPU. Most competing CPU boards do not have bus buffers.

Software and Manuals

The CE option adds Windows CE NET to the 301-06’s flash memory.  CE NET drivers are available for most Sensoray PC/104 boards.

The L option adds Sensoray’s Linux distribution to the 301-06’s flash. This is a configurable Linux file system that is accessible via the Ethernet port or one of the RS-232 ports.  Files may be transferred using the FTP (file transfer protocol).  Linux drivers are available for most Sensoray peripheral boards.

Sensoray has optimized Linux installation for the 301-06.  Although it is possible to recompile the Linux kernel, Sensoray does not offer technical support for this operation.
