I've decided to get into electronics and have a Gertboard with 26 pin cable and a Cyntech 40 way T board which has a 40 way cable. The Gert cable wont plug into the Pi3. Two possibilities: use the Cyntech cable to connect to the Pi3 or solder 26 pins to the Pi Zero and use that to "drive" the Gert.
Will either of these routes cause me problems and which would you recommend please? I have seen MarkHaysHarris777 suggestion of using individual connectors but I don't know which I need until I get started. I'm literally going to be fumbling in the dark copying others to get a feel for it. I'm competent with soldering iron and components, just not at thinking up circuits.
Thanks for looking.
I don't have a Zero, but have used my Gertboard with a B, B+ and Pi2.
Provided you connect the 26 pins of the Gertboard to the pins 1-26 of the Pi (by whatever means) you should have no problems - apart from changes in serial port on the Pi3, but this is not a hardware issue.
If you have an original Gertboard, rather than the model designed to mount "on top" of the Pi you COULD use a 26 pin cable, but you will find this doesn't "fit" because of the connector which won't fit between the pins. I made a cable with a 40 pin connector on one end (an old PATA HDD connector) to which I fitted a 26 pin connector on the other end by splitting off 26 wires.
The "on top" Gertboard can be used unchanged.
You could use a 26 pin connector on the Pi OR a 40 pin connector cutting off pin 27, 28 which are only used if you use a "HAT".
