KiCAD-Leadframes.zip

Leadframe PCBs for 48-pin, 40-pin, 32-pin and 28-pin DIPs. It adapts a DIP chip to a standard header either male or female. The lead frames can be bought on ebay here: https://www.ebay.ca/itm/296681581555
To solder the lead frame, it's best to cut the strip to length; i.e. for a 40-pin module, cut 2 20-pin strips. Leave them all attached and cut the frame holders after soldering.
