Low-cost basic SOIC break out boards. These are custom PCB boards that interface standard SOIC devices to standard .1" headers. 28-SOIC: Standard .6" spacing between pins. Will fit directly into a standard width (600 mil) DIP socket. For wide ICs (memories, drivers, 74s, etc).
Dimensions: 0.7x1.50"

40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers may be a better option for IC sockets.
