A smat way for connecting O'Maxi to a breadboard.

[flavigny]

Hello,
I have a lot of projects sharing ONE O'maxi.
I was bored to swap individual wires from GPIO 40 pins to my breadboards.
I noted that the 40 pin connector is the same as vintage IDE, so I reused a 40 wires (NOT newest with 80 wires) cable.
For safety, I fill with glue opposite plugs

Oooops, you will see later that it was better to fill opposite lines

I bought form ebay strip of pins, but as delivered (up) the pins have inequal lengths,I had to push them (firmly) to obtain equality (down):


Finally, I plug in breadboard:


As you see, two columns are lost due to the wrong choice of the filled sides; nextone will be better.
I will also probably split the board in two parts for better accessibility.
PO.

This is great idea!
Now... if I could only find old IDE cable...

Be careful about what IDE cable you use.
The newer 80 conductor IDE cables are not wired exactly as you might expect.
