Description

The RN41 is a small form factor, low power, highly

economic Bluetooth radio for OEM’s adding wireless

capability to their products. The RN41 supports

multiple interface protocols, is simple to design in and

fully certified, making it a complete embedded

Bluetooth solution. 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 is the perfect

product for engineers wanting to add wireless

capability to their product but don’t want to spend

significant time and money developing Bluetooth

specific hardware and software.

DS-RN41-V3.1 6/27/2011 Design Concerns 1. Reset circuit. RN-41 contains a 1k pullup to VCC, the polarity of reset on the RN41 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. Often a microcontroller or embedded CPU IO is available to generate reset once power is stable.
