| Centrino-like Mini-ITX board available passively cooled |
Jan. 16, 2004
 German single-board computer vendor Lippert is shipping a passively cooled version of its Centrino-like Thunderbird mini-ITX board based on an Intel Pentium M running at 1.3GHz. An actively cooled version running at 1.6GHz has been available since mid-December, 2003. Additionally, Lippert is readying a number of mini-PCI expansion devices and PCI riser cards for the boards.

Lippert specializes in single-board computers for embedded applications, and the Thunderbird targets gaming, entertainment, and other high-end applications. However, the company will also sell the boards in single units to hobbyists and enthusiasts. Be warned, though, that hobbyist kits are fairly expensive.
"Currently we sell an Thunderbird board with 1.6 GHz Pentium M and 512 MByte DRAM and low noise active cooler to end users for 875 Euro," notes Lippert founder Peter Lippert. "The passive version with 1.1 GHz Pentium M and 512 MByte DRAM costs 895 Euro. We hope that we can reduce the price in the future when Intel reduces the CPU prices or when the cheaper Celeron M is available (512 MB L2 cache instead of 1 MB in the PM [Processor Module])."
Without processor or RAM, suggested retail for the board is €379.

Both active- and passively-cooled versions of the boards feature a graphics subsystem based on the Intel 82855GME GMCH (graphics and memory controller hub), and both deliver the same graphics performance, according to Peter Lippert, despite the slightly lower clocking of the passively-cooled version. The 855GM is well-supported under Linux by GPL kernel drivers and recent versions of X.
If bought in quantity, available options include a 5V only power supply, extended temperature range, Compact Flash slot (as shown on bottom of board in photo above), and more.
The PCI slot supports only 3.3V PCI cards, but Lippert has designed two riser cards that broaden the options and will be available in February, 2004. "We have developed two 3.3V PCI riser cards with two PCI slots on each board," said Alfred Glass, a Lippert support engineer. "The first one uses level shifters to expand on two 5V PCI slots. So 5V PCI boards (older designs) can be used on Thunderbird. The second type of this PCI riser card routes the 3V3 PCI slot onto two 3.3V PCI slots."
The Thunderbird's 32-bit mini-PCI slot (Type IIIA) is "capable to hold all types of mini-PCI modules," according to Lippert, including Centrino wireless cards, modems, and more. Lippert has designed several mini-PCI cards of its own, including Firewire, Disk-On-Chip, and a four-port serial card.
