As shown in the bottom view of 

 on page 4, the CYBLE-0130XX-00 connects to the host board via solder pads on the backside

of the module. 

 and 

 detail the solder pad length, width, and pitch dimensions of the CYBLE-0130XX-00 module. 

To maximize RF performance, the host layout should follow these recommendations:

1. The ideal placement of the Cypress BLE module is in a corner of the host board with the trace antenna located at the far corner. 

This placement minimizes the additional recommended keep out area stated in item 2. Please refer to 

 for module 

placement best practices.

2. To maximize RF performance, the area immediately around the Cypress BLE module trace antenna should contain an additional 

keep out area, where no grounding or signal trace are contained. The keep out area applies to all layers of the host board. The 

recommended dimensions of the host PCB keep out area are shown in
