Last minute board layout!! | |||
How to link board to wires. After lots of thinking I have decided to use screw terminals, what digikey calls "terminal blocks - wire to board". | |||
Major benefit is that these terminals can have same spacing as old 0.1 inch DIPs and | |||
breakaway headers and hence no-solder boards! And they are more dense than the hand soldering loose wires would be (given my skill levels). | |||

2x [http://www.digikey.co.uk/product-detail/en/282834-2/A98333-ND/1150135 two-way] £ 0.76 | |||
So can use 0.1 breakaways in board design - just need to leave a bigger box for the screw terminal later. box dimension is 6.5mm by (pins * 2.54 + 0.5) mm. | |||
If I want to use pins in solder free boards need to lay out on 0.1 grid, and make sure the pins will work with the bus that these boards define, seems like a bit of work... more thinking reqd. | |||
