Gerard Braad made a fully annotated photo of the Bus Pirate on Flickr. Each pin, chip, and passive component is described in photo notes as you move your mouse over the image.

Bus Pirate v3 is available for immediate delivery from Seeed Studio for $30, including worldwide shipping. Each Bus Pirate purchased at Seeed Studio directly supports the development of this open source project.

Fantastic work, thanks for the tip!
