MCHPRN-42
Overview
The RN-42 is a small form factor, low power, Class 2 Bluetooth radio module for designers who want to add wireless capability to their products without the need for a host stack. It is a complete Bluetooth solution featuring an on-board antenna, FCC certification, and an embedded Bluetooth stack supporting version 2.1 plus Enhanced Data Rate (EDR).
Why Choose This Part
The RN-42 stands out for its ease of integration, requiring only a UART interface and no external Bluetooth stack to operate. It features low power consumption, drawing only 26uA in deep sleep while maintaining pre-certified compliance with FCC, IC, and CE standards to reduce time-to-market.
Applications
Getting Started
To evaluate the module, use the RN-42-EK evaluation kit, which provides a USB-to-Serial interface and status LEDs for rapid prototyping. Configuration is performed via simple ASCII commands over the UART interface, allowing for quick setup of pairing and baud rates without specialized IDEs.
