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:
2 SDA (level shifted to 5V)
3 SCL (level shifted to 5V)
5 SQW/OUT from clock (DS1338) at 5V level

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.
