Mechanical Dimensions
Notes: The WM2000 incorporates a jumper resistor that can be installed vertically (lengthwise) or horizontally. If it is installed vertically, the module will use the onboard chip antenna — this is the default "WM2000C" configuration. If the resistor is installed horizontally, then the module will use the U.FL antenna connector ("WM2000U" configuration). If the WM2000 is surface-mounted on the host board, special care is required to ensure the optimal operation of the onboard antenna. The two possible choices are:
