Review on Avanexpress DB9 Breakout Connector RS232 Serial 9 Pin Connector - Shop Now! by Brad Arthur

Revainrating 5 out of 5

Makes serial signal testing easier

I found it very easy to connect a jumper wire to the various pins I need. And if I flip these two backplanes and push them together from the bottom (where the foam is) where the connectors are pointing in opposite directions, then it's much easier to make direct pin connections (page 1 to pin 1, etc.) d.).

Pros
  • All signal ports are clearly named and labeled
Cons
  • No

Easy to use: large terminal blocks and nicely labeled.

These work great, the bottoms are padded so they won't short out on anything.
