I have RPI-3b and Sunfounder kit 1.0, and 40 pin GPIO extension board and cable.

Is it possible to use these device and components together?

PS: Sunfounder kit 1.0 is for RPI 1,2(b+).

  • I believe the GPIO layout of the Pi 3, Pi 2 and B+ is the same, so in that sense it should work.

  • I tried project from the URI: sunfounder.com/learn/category/… and it did not work.I just changed the GPIO pin numbers in C code. I through it might be compatibility issue. Jun 7, 2016 at 8:17
  • Could you try the project with the GPIO pin numbers left as they were?

  • Actually the project code was for 26 pin GPIO extension. There was a difference between pin numbers. I could not find 0 and 1 GPIO numbers from 40 pin GPIO extension board. That was the problem. Jun 7, 2016 at 8:39
  • I am sure there has to be some sort of conversion chart between the 26 pin GPIO and the 40 pin GPIO layout.

The Pi3B will operate in exactly the same manner as a Pi2B, Pi B+, Pi A+, and Pi Zero when used with the Sunfounder kit.
