Description

The RN-41-SM / RN-42-SM is a though hole, low

power and highly flexible Bluetooth socket module .

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 RN-41 / RN-42 delivers up to 3 Mbps data

rate for distances to 100M / 20M. The RN-41/RN-42

socket module is the perfect method for adding

Bluetooth wireless capability to existing products

without redesign, saving you significant time and

money.

The failure mode is short across GND and VCC. Use a 10KΩ resistor in series or a 10KΩ pull up resistor for input and output PIO’s respectively. • • • Make sure to connect a common ground when using the external TX, RX inputs 0 – 3.3Vdc.

RN-41-SM/RN-42-SM Data Sheet www.rovingnetworks.com 7/12/2010 Design Concerns 1. Reset circuit. RN-41-SM / RN-42-SM contains a 1k pullup to VCC, the polarity of reset on the RN-41 / RN-42 is ACTIVE LOW. A power on reset circuit with delay is OPTIONAL on the reset pin of the module. It should only be required if the input power supply has a very slow ramp, or tends to bounce or have instability on power up. Use microcontroller GPIO to control reset once power is stable.
