Hello!
I've just picked up an ID12 RFID chip to do my first Arduino project with. I failed to realise that the 2mm pin spacing on the chip would mean I couldn't connect it to my breadboard...I do however now realise that there is a breakout board available for it (http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=88&products_id=108) - this describes it as providing 'two 0.1" spaced headers', which leads me to think that although spaced a bit better, there won't actually be pins I can just drop into my breadboard. Then again, pictures I've seen online lead me to think that it can just drop in:

Is it simply a case of plugging the breakout board in, and then dropping it into my breadboard? Otherwise am I going to have to solder some connectors on?
I apologise in advance for my total lack of hardware knowledge.
