More information:
The RTC board has been designed so that as much of the expansion header is available as possible with a mixture of direct accessibility and pass through.

The board plugs into pins 1-6 and 23-28
Pins 7-22 can be accessed by plugging in connectors of the type reset switches normally use.
The pass through/ancillary connector (J3) on our board has:
1 GND
2 SDA (level shifted to 5V)
3 SCL (level shifted to 5V)
4 5V
5 SQW/OUT from clock (DS1338) at 5V level
6
7 Pin 3 (GPMC_AD7/SDMMC2_DAT7) via a 150R/Q1 for possible filing system activity LED (active low)
8 5V for GPIO LED if in use

We have fitted the board inside a Tigal case and being 1.1" high it is no higher than the USB/Network socket so should also fit other cases including Special Computing's acrylic case.
