Your basic SOIC break out boards. What’s the difference? The 8 Pin board is TINY. And you can’t beat the price! These are custom PCB boards that interface standard JEDEC SOIC devices to standard .1" headers.
This board has a standard SOIC-8 footprint with a layout that fits all standard JEDEC SOIC-8 devices.
40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers may be a better option for IC sockets.
