Board connectors

Several connectors are implemented on the B-WL5M-SUBG1 product:
• Five connectors are implemented on the MB1779 expansion board.
• Three connectors are implemented on the MB1880 fan-out board.
7.1

MB1779 STMod+ (CN1)

CN1 is an STMod+ connector (male). This connector allows interfacing the MB1779 board to:
• A host board (having an STMod+ female connector), so that the MB1779 is acting as an expansion board,
• An MB1880 STMod+ adapter board, so that the B-WL5M-SUBG1 product formed by the couple MB1779/
MB1880 is acting as a host board.
