The Pin matrix is a compact and visual to way to semi-permanently route signals or program devices, such as in early digital electronics or lighting control boards.

Disadvantages

The number of patches that can be made is limited and the proximity of signal wires in the matrix can cause

crosstalk In electronics, crosstalk (XT) is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, ...
