RN-42/RN-42-N Data Sheet www.rovingnetworks.com DS-RN42-V1.0 6/21/2011 Class 2 Bluetooth Module Features Fully qualified Bluetooth 2.1/2.0/1.2/1.1 module Bluetooth v2.0+EDR support Applications Available with on board chip antenna (RN- 42) and without antenna (RN-42-N) Cable replacement Postage stamp sized form factor, 13.4mm x Barcode scanners 25.8 mm x 2mm (RN-42) and 13.4mm x 20 Measurement and monitoring systems mm x 2 mm (RN-42-N) Industrial sensors and controls Low power (26uA sleep, 3mA connected, 30mA transmit) Medical devices UART (SPP or HCI) and USB (HCI only) Barcode readers data connection interfaces. Computer accessories Sustained SPP data rates - 240Kbps (slave), Description 300Kbps (master) The RN42 is a small form factor, low power, highly HCI data rates - 1.5Mbps sustained, 3.0Mbps economic Bluetooth radio for OEMs adding wireless burst in HCI mode capability to their products. The RN42 supports Embedded Bluetooth stack profiles included multiple interface protocols, is simple to design in and (requires no host stack): GAP, SDP, fully certified, making it a complete embedded RFCOMM and L2CAP protocols, with SPP Bluetooth solution. The RN 42 is functionally and DUN profile support. compatible with RN 41. With its high performance on chip antenna and support for Bluetooth Enhanced Bluetooth SIG certified Data Rate (EDR), the RN42 delivers up to 3 Mbps Castellated SMT pads for easy and reliable data rate for distances to 20M. The RN-42 also PCB mounting comes in a package with no antenna (RN-42-N). Certifications: FCC, ICS, CE Useful when the application requires an external antenna, the RN-42-N is shorter in length and has RF Environmentally friendly, RoHS compliant pads to route the antenna signal.
