Typical RSSI characteristic is shown below (this is for indicative purposes only and is not a guarantee of
actual RSSI characteristics):
Module mounting considerations
The module may be mounted vertically or bent horizontal to the motherboard. Good RF layout practice
should be observed – in particular, any ground return required by the antenna or feed should be connected
directly to the RF GND pin at the antenna end of the module, and not to the OV pin which is intended as
a DC ground only. All connecting tracks should be kept as short as possible to avoid any problems with
stray RF pickup.
If the connection between module and antenna does not form part of the antenna itself, it should be made
using 50
unused PCB area around the module with ground plane.
The module may be potted if required in a viscous compound which cannot enter the screen can
Warning: DO NOT wash the module. It is not hermetically sealed.
