I'll begin from a little fail with photodiode Mux.

At beginning of my PCB testing input block - pdotodiode input MUX I realized what I forgot to add mux switching pins and Logic high (+2.5v) pins for mux controlling:( That's was my second fail and next board hacking for adding this additions.

Added two pin headers for Mux logic control and three pin header for logic control - Logic High.

Mux switching tested by manually input switching between four inputs with Logic control inputs pins.
