Hi thanks yes it does seem to be 0.5mm, though only measuring with a ruler so hard to be exact. The fatter tops of the pins seem to be 0.5 apart but of course where they narrow out there is a wider gap.
Is there any kind of socket that I can use that will accept this chip, then I could just solder the socket to the pcb. And the component made in fritzing could then be for the socket instead?
Thanks again for any help
