4.2Mounting the blu2i Module onto the application platform

There are many ways to properly install the Module in a host device. An efficient approach is to mount the PCB to a frame, plate, rack or chassis. Fasteners can be M1.8 or M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets in 2.2mm diameter holes. Note that care should be taken to ensure the head of the fixing does not interfere with the circuit. Nylon fixings are recommended. In addition, the board to board connection can also be utilized to achieve better support.

The antenna (Brown square component on top side of PCB) must not be influenced by any other PCBs, components or by the housing of the host device. The proximity of the antenna to large metallic objects can affect the range and performance of the system. Designers should carefully consider the location of the module and the type of enclosure material that is used.

To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat against the host device.

4.3 Board to Board Connector

This section provides specifications for the 40 way board-to-board connector which serves as physical interface to the host application. The receptacle assembled on the blu2i Module is type Hirose DF12C.
