Strategic Test Corp. has launched a tiny, inexpensive single board computer (SBC) based on a 400MHz PXA255, an Intel XScale processor popular in PDAs and smartphones. The Triton-Eco SBC comes with Linux 2.6 pre-installed, and costs $135/$99 in quantities of 10/1000.

The Triton-Eco is based on the DIMM 144 form-factor, and measures just 1.25 x 2.3 x 0.26 inches (67.6 x 36.6 x 7.3 mm) including the DIMM 144 connector.

Strategic Test launched what it called the world's first PXA255 embedded CPU module with a DIMM 144 form-factor in September, 2002. Boards based on the DIMM 144 form-factor — and in some cases compliant with the dimmPCI PCI standard — are available from uClinux specialist Arcturus (uCdimm), JumpTec (DIMM-PC/586, Forth-Systeme (DIMM-520 SBC) and others; visit our Tiny SBC Quick Reference Guide for more.

Strategic Test's Triton-Eco offers I2C and JTAG interfaces, 4 serial ports, an LCD controller, and a PCMCIA / CF interface. It requires a single 3.3V supply, and supports ultra-efficient sleep modes through “unique Programmable Core Logic power generation and clock-rate selection,” according to Strategic Test.

The board includes 16MB of SDRAM, and 8MB of flash. It comes with RedBoot firmware, and a Linux kernel 2.6 kernel pre-installed. Windows CE support is under development. I2S and AC97 interfaces are available as options. Additional details are available online

The new Eco board is the fifth in Strategic Test's Triton line of PXA255-based CPU modules. Triton options include a variety of PXA255 CPU speeds, up to 64 MB SDRAM, and 32 MB Flash, 10/100 Mbps Ethernet interfaces, and an extended operating temperature range (-40 to +85 degrees C) available in the LP model (pictured above). The smallest Triton board, the XXS, measures just 32 x 59 x 6.6 mm.

Strategic Test has offices in Stockholm and Boston, and in addition to modules, offers custom design services to clients worldwide.

Intel's PXA255 is used in many mobile embedded devices, including the Sharp Zaurus PDA, Samsung SCH-i519 smartphone, NexGen City NexPaq VoIP walkie-talkie, and the Posio PX-30 hackable wireless router.
