This listing is for 4 adaptor boards only. One side of the board has solder pads for SOIC-16 packages and the other has pads for the smaller SSOP-16 package. The second photo shows a typical application of the board, with header pins and a 74HC595 soldered onto it.

There are a number of vendors out there selling this sort of thing, but this design fits into a DIP-16 socket, is more compact and includes the possibility of adding the power supply decoupling capacitor close to the chip. The capacitor pads are connected to pins 7 and 14, which is good for most logic ICs. It is suggested that the header pins be soldered in first, cut flush then the IC soldered on top.

I am happy to combine postage for multiple orders.
