Title: Very odd keyboard matrix on mt Alps SKFL T3200
Post by: matt-taco on Sun, 24 September 2023, 19:09:27

This board is just a matrix, no logic. I am trying to wire it to a raspberry pi pico, and, it is really odd. In the attached picture, I am providing just one example of how the matrix is layer out. The pin shaded with black, and the black box is on "column"

There is also 3 grounds, I think.

I really wish the service manual had the pinout.

It looks like the matrix has diodes. Then it does not matter for its function that it is complicated.
