Picked up this shield from Mouser. Looks like an official arduino proto shield, but I couldn't find any info on it on this site.
Is this an official board or a clone? Judging by the silk screen I can see where some of the bag of parts that it came with goes, but looks like there's lots of extras. I was hoping there was some documentation somewhere to look at.
Comes with the board, 40 pin header strip, 6 pin ISP header, 3 5mm LEDs (Red, Green, Yellow), 2 switches, and 15 resistors (5 ea. 10k, 1k, 220).
Brings up the ISP header and reset from below only from what I see. Gives 2 dedicated spots for LEDs for use as you please, +5vdc and GND rails, a 14 pin SMD breakout section and a 20 pin DIP breakout section in addition to general prototyping area.
Judging by the pictures on Mouser, I got a completely different board than what they have pictured. Mine has the DIP section and an Arduino logo on it.
A "protoshield" like this doesn't usually have much actual circuitry. It is designed to hold various standard components (connectors to the board below, reset switch, LEDs with current limiting resistors, etc), and allows you to connect them (plus additional components) however you want to achieve relatively simple but "professional looking" custom shields - what you might want to do if your circuit is so simple and so cheap that it really doesn't make any sense to design a PCB, but you want more physical "solidness" than you'd get with free space wiring or a protoboard.
You can look at one of these similar protoshields to get an idea how they are put together and used:
