I had figured that is someone wanted to have I/O signals via a connector, they could solder a single row header to the prototype area. However, the double row is more compact and providing a space for it keeps I/O from eating into the proto area. I've put your connector on the board with 10 labeled pads coming out so that it can be hooked up any way someone wants. I'm thinking this would not come installed, but the pads would be there. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
