Claims:1. A connector to couple a card or module to a motherboard, the connector comprising:
connector housing; and
a plurality of pins, each of the plurality of pins including two ends including a card or module-facing end to couple with the card or module and a motherboard-facing end to couple with the motherboard;
each of the plurality of pins including a middle section in the connector housing, wherein one or both of the ends include one or more bends relative to the middle section; and
the plurality of pins including alternating signal pins and ground pins, the signal pins having an opposite orientation relative to the ground pins.
, Description:FIELD
[0002] The descriptions are generally related to connectors for coupling modules (such as memory modules) or devices with a printed circuit board such as a mother board, and more particularly, to connectors with a pin orientation that may enable a reduction in crosstalk.
BACKGROUND
[0003] Various technologies exist for connecting cards and modules with a printed circuit board (PCB) such as a motherboard. It is possible to couple electronic components directly to a motherboard, however, it is common to use a connector between the motherboard and the card or module to enable removably coupling the card or module with the motherboard.
[0004] Connectors typically have pins to couple with contacts on both the module and motherboard sides. Some pin configurations can result in significant crosstalk. For example, high frequency signal pins that are in close proximity may cause signal quality degradation due to crosstalk.

DETAILED DESCRIPTION
[0015] Connector pin orientation to reduce crosstalk is described herein. In one example, a connector includes rows of pins with a staggered orientation. For example, a connector to couple a card or module to a motherboard includes connector housing and a plurality of pins. Each of the plurality of pins includes two ends including a card or module-facing end to couple with the card or module and a motherboard-facing end to couple with the motherboard. Each of the plurality of pins includes a middle section in the connector housing, wherein one or both of the ends include one or more bends relative to the middle section. The plurality of pins includes alternating signal pins and ground pins, wherein the signal pins having an opposite orientation relative to the ground pins.
