Signals, Interfaces and Pins
Module signals connected to the B2B connector:
|B2B Connector||I/O Signal Count||Voltage Level||Notes|
|J2||4||parallel to J1|
|J3||4||parallel to J1|
J1 is the main CRUVI connector and should be used to connect the CR00040 to any CRUVI baseboard with CRUVI LS connector fitter. J2 and J2 are un-populated 100 mil pin-headers that allow solder-in pin-headers to use the CR00040 with solder-less breadboards or fly-wires.

Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).
Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
