Intel has officially unveiled the Galileo Gen 2, a redesign of the original Galileo development board that looks to address issues with its predecessor.
Intel's Galileo Gen 2 board offers a number of improvements over its predecessor, although retains the low-power and low-performance Pentium-based Quark chip.
The original Intel Galileo was launched by the company in October 2013 as its first hobbyist-themed developer board. Developed in conjunction with the Arduino project and boasting its official certification, the Galileo was the first outing for Intel's low-power Quark chip. Although promising full Arduino compatibility with embedded Linux and the familiarity of the Pentium x86 instruction set architecture, the board launched with a number of issues that made it a less than popular choice with hobbyists.
Those who found the 400MHz Quark chip too slow for their projects will be disappointed to hear that the Gen 2 makes no changes in this regard: it's still powered by the same 32-bit single-core chip as its predecessor. Improvements have been made to the way the general-purpose input-output (GPIO) pins operate, however, boosting their performance considerably and improving their compatibility with Arduino shields and accessories. The board's pulse-width modulation (PWM) resolution has been increased to 12 bits, while the esoteric RS232-level serial connection provided by a 3.5mm jack has been replaced with the more standard six-pin TTL serial connectivity found on rival boards.
Additional improvements include power supply circuitry that can accept inputs between 7V and 15V, replacing the fixed-voltage input of the original. This should make the Galileo better suited to embedded projects that use battery power, although its high power draw compared to a microcontroller-based Arduino may still put many off using it in such a manner.
The new board will replace the original model, and is expected to sell at the same price point of £55 in the UK.
