Flat cable GPIO for Protoboard

Mon Feb 11, 2013 9:33 am

I decided to make a cable interface for input and output of the Raspberry Pi (GPIO) for connect to Protoboard.

The GPIO connector has 26 pins. I found in my scrap, flat cable with 26 pins but one pin closed in the connector, ie with 25 pins.

I saw in the description of the GPIO pins that is ground pin .

So it will not be missed, because there are other ground pins on GPIO. Then I will make a hole in the cable connector in order to connect the GPIO.

I used a few bars of pins (easy to find). I crumpled the tips of the bar with smaller pins and then soldered the two bars - see the photos.

It was very good. Although not tested.

Remember that the interface uses levels of 3.3 V.
So do not plug in circuits that use 5V!

I've been trying to create one of these myself, but with a smaller footprint.. Though, I may end-up making this version myself.. The hard part, is finding a source for PC board that is plated through.. Radioshack no-longer has anything other than single-sided..

I know that making stuff is often fun - I do it myself a lot, but sometimes it's easier to just buy something - especially if not 100% confident in your own design/solder abilitys...

I have one of their original "cobbler" boards, the the latest "T" one is looking like it might slip into my next order: https://www.adafruit.com/products/1105

(Although I understand getting stuff into Brazil is somewhat problematic at times though!)

seems to be a selection of breakout boards here: http://www.hobbytronics.co.uk/raspberry-pi

i've never seen a direct ribbon cable to breadboard pins adaptor though.

i generally just use male-to-female header leads for prototyping.
