Tibbit Form Factors and Colors
Tibbits are divided into Tibbit modules ("M" devices) and Tibbit connectors ("C" devices). There are also hybrid ("H") Tibbits that combine the two.
"M" and "C" devices can have single ("1") or double ("2") width. They can also be short ("S") or tall ("T").
Tibbit connectors also have convenient hooks that secure them on the board's edge.
