PIFACE Shim RTC ADD-ON Board, Real TIME Clock, Raspberry PI

The product I received is not the PiFace SHIM RTC and does nott look like the photo in this ad. The true Piface SHIM RTC is a very thin PC board designed to be sandwiched beween the raspberry pi and another hat. The true PiFace Shim relies on a clever off-setting of some of the connector holes to obtain a good electrical connection to the Pi's GPIO pins. The RTC I received has a 6-pin socket designed to plug on top of the Pi (which will not work for my needs) and uses a diffrent battery and RTC chip than the true PiFace SHIM RTC.

Cute board. Works well enough. Has enough space on the back for FCC rules Part 15, sections 1 and 2 as well as an inexplicably large PiFace RTC logo, an eagle, some sort of G logo, a funky looking backward comma, a circle-check mark logo, a no trash logo, Element14 in two places, notes that it's designed in Cadsoft Eagle, and a confoundingly large CE logo (JUST ON THE BACK!) - but not pin numbers, polarity indications, hints to positioning, etc. Of course there's no documentation in the package, or the listing here, but the logos are cool. Genius.
