CYBLE-012011-00
Pad Connection Interface
As shown in the bottom view of
Figure 1
on page 5, the CYBLE-012011-00 connects to the host board via solder pads on the backside
of the module.
Table 2
and
Figure 2
detail the solder pad length, width, and pitch dimensions of the CYBLE-012011-00 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. Refer to
AN96841
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
Figure 3
(dimensions are in mm).
