Rpi3 Bv1.2 & Gertboard 21-Oct-2012

Hi all,
I'm new to this so please be nice and I appreciate any help I receive.

I have a windows programming background and did a bit a electronics many years ago and now want to get back into it (mainly for controlling Lego & using the Arduino functionality and sending data back to the Pi3).

I have purchased a Raspberry Pi 3 B V1.2, touch screen, and a GertBoard (21-Oct-2012), plus a 26 pin ribbon cable for connecting the Pi and the gertboard together (last week). This is where the problem starts the Pi3 has a 40pin GPIO and the GertBoard has a 26 pin. Everything I read and see points to the 2 just working and clicking together (I am probably missing the obvious).
Does anyone have any basic instructions on connecting the Pi3 and the Gertboard together? (And yes I have probably missed the detail somewhere and I apologise for this).

Thanks
Michael

Connect the Gertboard to the 26 pins furthest away from the USB and RJ45 connectors. Also, if not using the ribbon, place the Gertboard so it does not stack over the RPi, they appear as to be side by side. If using the ribbon cable, make sure the same arrangement applies. Using a ribbon cable does give you access to the other 14 pins which would otherwise be hidden beneath the Gertboard.

Thanks Baantonia. I was going to use the gertboard for interfacing with Arduino but feels like I should abandon the idea on the Gertboard, what do you think?

Never used an Arduino so I cannot comment regarding interfacing directly or indirectly. Note: GPIO 0 and 1 on the Gertboard becomes GPIO 2 and 3 when connected to anything other than an original Pi B. However, the Gertboard does offer some level of protection for the RPi as the IO connections nearest the LEDs are buffered and can only be set to input or output by the means of jumpers, don't forget the GPIO mode for the pins on the Pi has to be set accordingly also.

Thanks again Baantonia, will keep a note of that.

I have used my GertBoard with a Pi B+ and Pi2 so it should work with the Pi3, which all have the same connector and functionality on pins 1-26 as the original Pi.

The GertBoard was, and remains, an excellent tool for connecting to GPIO, and provides safe, buffered access to the GPIO.

NOTE You can not (easily) use a cable to connect the 2, as the GertBoard has a female connector. I did post a method of soldering a male connector to the GertBoard (in this category).

If all you want to do is use Arduino functionality an Arduino Pro Mini (or a Uno) may be a better and cheaper solution. The GertBoard provides additional on board drivers.

I've used ribbon cable with dupont female to male jumper connectors to get access to the other GPIO pins otherwise hidden by the Gertboard. It's not pretty and doesn't allow the Gertboard to sit flat but it works. I agree, the Gertboard is an excellent tool!

ok thanks milliwatts and banntonia, think i might get a credit on the gertboard and get an arduino and start to crawl before i walk.
