SiP
Module Data Sheet
The BGM11S Blue Gecko
Bluetooth
®
SiP Module family is targeted for applications
where ultra-small size, reliable high performance RF, low-power consumption and easy
application development are key requirements.
At 6.5 x 6.5 x 1.4 mm the BGM11S module fits applications where size is a constraint.
BGM11S also integrates a high performance, ultra robust antenna, which requires mini-
mal PCB, plastic and metal clearance. The total PCB area required by BGM11S is only
51 mm
2
. The BGM11S has Bluetooth, CE, full FCC, Japan and South-Korea certifica-
tions.
The BGM11S also integrates a
Bluetooth
4.2 compliant Bluetooth stack and it can also
run end-user applications on-board or alternatively used as a network co-processor over
one of the host interfaces.
BGM11S SIP modules can be used in a wide variety of applications:
•
•
•
•
•
•
Wearables
IoT end devices and gateways
Health, sports and wellness devices
Industrial, home and building automation
Smart phone, tablet and PC accessories
Beacons
