J-COM

J-COM is the pair of connectors which serves as interface between the XB1 COM Express Module and the carrier board. The assembly is composed of two double-row, high speed, 0.5mm pitch plugs. Each row has 110 leads, i.e. J-COM provides 440 contact positions in total. The COM.0 specification assigns each row a letter A, B and C, D. For Type 1 COM Express modules, rows A and B are sufficient (single connector, 220 leads). In addition, rows C and D (dual connector, 440 positions) are required for extended functionality incorporated into Type 2 modules such as the XB1.
