In the Slew Rate vs Rise Time video, I used this little breakout board. The bottom side is a continuous copper plane. On the top, the square pins have solder pads that you can connect to the top and bottom copper pour. The idea is to provide as much ground as possible.
There are a few 2.54mm spaced holes for each pin. These allow for through-hole passives or 0805 surface mounts.
The headers on the "top" and "bottom" of the board are connected to each other and intended for power rails.
Originally, I designed the board for SOIC-8. I didn't think of DIP compatibility. So on version 1, you can get a DIP-8 to fit, but you have to bend the pins a bit.
Last, the PCB fab I used can, apparently, print silk directly on HASL. I assumed they wouldn't, so I didn't remove any of the top-layer silk. Oops. In the microscope shot below, you can see white silk screen around the "solder jumper" footprint pads. The silk does help contain the solder when shorting them, so that was nice.
Anyway, I found the board worked well, especially compared to a breadboard.
$32 for qty 5 shipped from an Asia-based PCB house.
