Abstract: An arrangement including a first circuit board having a contact surface for contacting of a connecting element, a second circuit board, and a connecting element. The contact surface has a central contact point and a concentric ring surrounding the central contact point. The connecting element which is electrically contacted at a first side with the second circuit board and which at a second side in opposite relationship to the first side includes a first spring element at least one second spring element. The first spring element is electrically contacted with the central contact point of the first circuit board and the at least one second spring element is electrically contacted with the concentric ring of the first circuit board.

Abstract: The present invention relates to a radio module which has at least two operational modes; a passive operational model wherein an external microprocessor device is connected to the radio module as an external electrical device, the radio module is used as a modem for the external microprocessor device and the radio module can be controlled by the external microprocessor device with the aid of modem control signals, preferably AT commands, and at least one active operation model wherein at least one actuator or sensor is connected to the radio module as an external electrical device, the radio module controls the at least one actuator or sensor and/or acts as a read-out therefore and can be controlled from the outside with the aid of the radio device.

Abstract: Printed circuit board having a plug connection The present invention relates to a printed circuit board for a radio module which has a connection on the printed circuit board side having contact points for selectively connecting a plug from a number of plugs of a predetermined plug type which have various contact points fitted to them, it being possible, depending on the selection of the plug from the number of plugs which have various contact points fitted to them, to fit a plug-specific selection of contact points of the connection on the printed circuit board side.
