CYBT-343052-02
Pad Connection Interface
As shown in the bottom view of Figure 2 on page 5, the CYBT-343052-02 connects to the host board via solder pads on the backside
of the module. Table 2 and Figure 3 detail the solder pad length, width, and pitch dimensions of the CYBT-343052-02 module.

To maximize RF performance, the host layout should follow these recommendations:
1. Antenna Area Keepout: The host board directly below the antenna area of the Cypress module (see Figure 2 on page 5) must not
contain ground or signal traces. This keepout area requirement applies to all layers of the host board.
2. Module Placement: The ideal placement of the Cypress Bluetooth module is in a corner of the host board with the PCB trace
antenna located at the far corner. This placement minimizes the additional recommended keepout area stated in item 2. Refer to
AN96841 for module placement best practices.
