Taiwan-based Aewin has introduced a pair of Intel-powered computer-on-module (COM) products, along with an accompanying evaluation baseboard with "digital signage" features. The CM-7300 and CM-7301 are implemented as COM Express modules and target high-performance embedded applications such as medical, test/measurement, gaming, entertainment, and security devices, according to the company.

The two modules appear to be nearly identical except for processor support. The CM-7300 works with a range of socket 479 Pentium M and Celeron M CPUs with either 400 or 533 MHz front-side bus (FSB) speeds, and utilizes Intel's 915GM chipset. The CM-7301, meanwhile, accommodates Core Duo Pentium M processors with an FSB up to 667 MHz, and incorporates a 945GM chipset. Both modules feature one DDR2 SO-DIMM socket, for up to 1 GB of SDRAM.

Features common to both modules, according to Aewin, include:

Display:
- dual 18-bit LVDS up to 1600 x 1200
- analog VGA up to 2048 x 1536
- TV out
- PCI-Express x16 graphic expansion port
Storage -- 2 Serial ATA 150 ports
I/O ports:
- gigabit Ethernet
- 8 USB 2.0
- AC97 audio
- parallel port, I2C, 8x GPIO

The modules also differ in their expansion capabilities:

The CM-7300 has a 3x PCI 2.2 32-bit 33 MHz expansion interface that supports up to four Req/Gnt pairs
The CM-7301, on the other hand, features a PCI-Express x16 port plus five additional ports that can be configured as either five x1 or one x4 plus one x1; it also supports a PCI 2.3 32-bit 33 MHz expansion interface with up to four Req/Gnt pairs

According to Aewin, the BB-103 baseboard provides connectors and signal conditioners for a range of peripheral and expansion ports, including:

1 x PCI 2.3 32-bit 33MHz
1 x PCI-Express x16; 4 x PCI-Express x1
1 x 54/34 Express card slot
Video interfaces:
- 2 x 18-bit LVDS
- DVI-I connector with both digital video & analog VGA support
- TV out -- AV connector and S-terminal
Drive interfaces -- IDE; 2 SATA; FDD
Other I/O ports:
- RJ45 Ethernet
- 8 x USB -- 6 external, 2 internal
- 2 x RS-232
- PS/2 keyboard/mouse
- audio -- line in, line out, mic in
ATX power connector

Aewin typically supports its board-level computers and accessories under Windows XP, Windows XP Embedded, and Linux. However, the company had not confirmed this support for these boards by publication time.

All three products appear to be available now. Pricing was not disclosed.
