DESCRIPTION
The RN41XV and RN42XV are small form factor, low-
power Bluetooth radio modules offering plug-in com-
patibility for the widely used 2 x 10 (2-mm) socket typi-
cally used by 802.15.4 radio modules.
Based on the popular 2 x 10 (2-mm) socket footprint
often found in embedded applications, the Roving Net-
works’ RN41XV and RN42XV modules provide Blue-
tooth connectivity in legacy and existing designs that
may have been based upon the 802.15.4 standard.
The RN41XV Class 1 Bluetooth module is based on the
RN41, and the RN42XV Class 2 Bluetooth module is
based on the RN42. These modules are simple to
design in and are fully certified, making them a com-
plete embedded Bluetooth solution. The RN42 is func-
tionally compatible with the RN41.
The Class 1 RN41 module has a range up to
100 meters. The Class 2 RN42 module has a range up
to 20 meters.
