Double Sided breadboard for test bed

[Bpk9p4]

I was wondering if anyone had ever run across a double sided bread board where you can plug in cables from the front and back.

The reason i am wanting this is i am making a test bed box for are software team and i want an easy way to get PWM cables from inside the box to outside. I know i could just drill a whole but it would be nice to be able to quickly connect PWM cables without having to run wires in and out of the box.

To give you an idea of what i am trying to do i attached a picture

If you put your motor speed controllers inside the box, as they are in the one pictured, you don't need PWM cables to be run from the inside to the outside.

When we did an integrated control box on our Lunacy robot, we connected sensor wires from the outside using a DB-25 cable. We cut off the Centronics end of an old parallel printer cable and ran its wires directly to the encoders and optical sensors and limit switches, with only a couple of extensions needed. For development and testing purposes, we occasionally had the control box on the software bench with a DB-25 extension cable running between it and the connector on the robot.

That is correct for all the motor i have run the PWM cables internally. However i am wanting something for sensors.

The DB-25 cables is a good idea. Did you use the end of the cable like a quick connect or did you solder the wires on?

[Alan Anderson]

Normal three-pin connectors were plugged in to the DIO pins and the analog breakout. The other end of those wires were soldered to the back side of the DB-25S connector on the control box.

We did omit the +5 wire for circuits going to limit switches, and we only connected the SIG pin for the second digital input going to each of the wheel speed encoders.
