PiFace CAD2 covers unused GPIO pins on Pi3B

stuartlogie

Hi everyone

 

When I connect my PiFace CAD2 directly to my Raspberry Pi 3 Model B it uses the first 26 GPIO pins but also partially covers the remaining 14 pins, making them a challenge to access and use. I would like to lift the CAD up a bit so I can still connect jumper cables to the rest of the GPIO pins. I have seen a 26 pin GPIO connector header extender - Extra Tall - advertised on ModMyPi (https://www.modmypi.com/raspberry-pi/gpio-and-breadboarding/26-pin-gpio-connectors/26-pin-gpio-connector-header-extender… ). Would this be the right kind of thing to use, or how could I go about this? I've looked at a 26 pin cable; however I think it might be too wide at the ends. Another alternative is to use 26 jumper cables though this may be a bit cumbersome.

 

I have worked around this by stripping off the plastic ends of jumpers and bending the inner metal connectors to fit under the CAD2. This is quite a risky approach however. I don't want to short out my Pi. It also makes the connectors more fragile.

 

Has anyone done this before?

 

Another question, is it advisable to use the remaining pins with the CAD2 connected? Do I run the risk of drawing too much power and burning out my Pi?

 

Thanks a lot

Stuart

 

PS: here's my Pi with CAD2 and 3 GPIO pins connected.
