Connectors that may be used to connect optional or daughter cards or modules to main logic boards or motherboards in electronic devices. These connectors may have a reduced effective height and may be able to support high data rates. Cards in these connectors may be secured in place in an electronic device to avoid being inadvertently dislodged. The connectors may accept a card such as a solid state drive, memory card, subscriber identification module, or other type of card. Examples may also provide cards to be inserted in the connectors and boards to support the connectors.
