RN41-DS
1.0 DEVICE OVERVIEW
The RN-41/RN-41N module is a small form factor, low
power, class 1 Bluetooth radio that is ideal for design-
ers who want to add wireless capability to their prod-
ucts without spending significant time and money
developing Bluetooth-specific hardware and software.
The RN-41/RN-41N supports multiple interface proto-
cols, is simple to design in, and is fully certified, making
it a complete embedded Bluetooth solution. With its
high-performance, on-chip antenna (RN-41) or exter-
nal antenna (RN-41N), and support for Bluetooth EDR,
the RN-41/RN-41N delivers up to a 3-Mbps data rate
for distances up to 100 meters.
The module provides FHSS/GFSK modulation and 79
channels at 1-MHz intervals. 128-bit encryption
ensures secure communication.
The module can be configured locally via the UART or
over-the-air. To support instant cable replacement,
auto-discovery/pairing does not require software con-
figuration. Additionally, the module supports auto-con-
nect master, I/O pin (DTR), and character-based trigger
modes
