InHand Electronics has introduced the fourth generation of its tiny (2.4 x 3.4 inches) Fingertip single-board computer (SBC). The Fingertip4 runs Linux on an Intel PXA270 processor, and features a new peripheral expansion scheme based on a variety of parallel and serial interfaces.

The Fingertip4 is a successor to the PXA255-based Fingertip3 with a number of enhancements, according to InHand. The new board accomodates up to 128 MB of RAM and 64 MB of Flash, up from 64 MB and 32 MB respectively on the Fingertip3. Maximum processor speed is 512 MHz, up from 400 MHz. Onboard peripheral interfaces include an LCD controller with touchscreen and backlight support, USB Host and Client ports, three UARTs, and AC97 audio. The SBC also includes both CompactFlash and and SD card slots.

InHand says the Fingertip4 leverages the company's BatterySmart power management software suite to control performance and power consumption, by allowing greater responsiveness to voltage and frequency changes. Additionally, the board implements a new power supply design that boosts power delivery efficiency and provides real-time voltage adjustment features that extend battery life.

The Fingertip4 is expected to be available in October, with support for both Linux and Windows. Development platforms start at $2,995, and the Fingertip4 SBC by itself will be available for volume purchase, InHand says.
