Description
The RN41 socket module is a though hole, low
power, highly Bluetooth radio. This module supports
SPP/DUN and HCI Bluetooth interface protocols, is
simple to design in and fully certified. With its high
performance on chip antenna and support for
Bluetooth® Enhanced Data Rate (EDR), the RN41
delivers up to 3 Mbps data rate for distances to
100M.. The RN41 socket module is the perfect
adding Bluetooth wireless capability to existing
products without significantly redesign your
application saving you significant time and money.

Pin Description
All signals on
Header A
except
pins 4, 5, 6 and 7
have the following
logic levels.
Input logic level LOW
is from -0.4 v to 0.8
V, input high is from
2.1 to 3.4V.
Output logic level
LOW max is 0.2 and
output HIGH is
minimum is 2.8.
All I/O’s except reset
default to weak pull
