Parallax Inc Propeller USB Development Board 32810

This board is for Propeller projects that need a permanent home. Its low cost, feature-rich, and simple design is ideal for most any project using the Propeller P8X32A multicore microcontroller. The core Propeller programming circuitry is built into the board, with access to all 32 I/O pins.
Thoughtful features such as power and over-voltage LEDs and well-placed labels on both sides of the board help make circuit-building fast and accurate. The reset button, USB, power, and optional connectors are all set at right angles for easy access when the finished project is mounted in an enclosure.

The Propeller™ 1 microprocessor chip makes it easy to rapidly develop embedded applications. Its eight 32-bit processors (COGs) can operate simultaneously, either independently or cooperatively, sharing common resources through a central hub. The developer has full control over how and when each cog is employed; there is no compiler-driven or operating system-driven splitting of tasks among multiple cogs. A shared system clock keeps each cog on the same time reference, allowing for true deterministic timing and synchronization. Two programming languages are available: the easy-to-learn high-level Spin, and Propeller Assembly which can execute at up to 160 MIPS (20 MIPS per COG).
