Hardware Connnection
The Raspberry Pi can share and connect up to three LED dot matrix screen panels. If there is only one panel, just connect the pins corresponding to the 😄 mark in the table below. [2]💥 and [3]💧 need to share the connection of the second and third panels at the same time.
The following table adds some icons for better visual distinction: [1]=😄, [2]=💥 and [3]=💧.
