raspberry/matrix

The humanoid on the picture is not mine its Anice charaf's work , i'm currently working on a project which will include some properties of the humanoid on the picture.
the matrix creator card occupies all raspberry gpio but it provides the pins that i ve shown in red as raspberry gpio there are 17 pins , the matrix chip contain 8 microphones that s why it should be mounted to humanoid head as in the picture so the microphones could detect vocal commands , the 17 pins in red will be used to control motors , sensors etc
