What is the Propeller?
The Parallax Propeller is a 32-Bit 8-Core microcontroller. Chance are you've already seen a few Propeller Powered projects like:
OpenStomp Coyote-1: open source digital guitar effects pedal
Music Demo (.mp3)
The Replica 1, an Apple 1 Clone
ybox2, DIY Networked Set-top Box
and plenty more. The Propeller is commonly used because it's high performance, has easy video output, and offers a lot of I/O.
So What is the Propeller Platform?The Propeller Platform puts the Prop on a circuit board with voltage regulators, memory, a crystal, and connectors to other modules. It's a lot like the Arduino with a few improvements on the basic idea;
1 - Modules (a.k.a. shields) can be connected to each other on top and bottom. For example, you might have a Propeller module in the middle, an LCD UI on the top, and a prototyper on the bottom.
2 - Pin spacing is .1". The space between sockets is .2", too. This makes the Platform compatible with breadboards, and it lets you use Platform modules in combination with other project boards.
3 - The board footprint is 3.8" x 2.5", which is the same footprint as ExpressPCB's MiniBoard service, so adding your own custom module is inexpensive and straightforward.
4 - They're well documented. They're featured in Jon Williams' column in Nuts and Volts and the Propeller Platform Module will be the basis for many of projects described in his upcoming columns.
5 - They're Public Domain. Module designs use the MIT license, giving you more flexibility than more restrictive licenses like Creative Commons Share-Alike. Templates and specifications can be downloaded here.
The Propeller Platform is available as a kit or pre-assembled from Gadget Gangster.
