The RN42 is a small form factor, low power, multi-interface protocol, Class 2 Bluetooth radio that is simple to design in, and is fully certified for designers who want to add a complete embedded Bluetooth solution to their products fast. The RN42 delivers up to 3 Mbps data rate for distances up to 20 meters with its high-performance PCB trace antenna and support for Bluetooth EDR. The RN42 is also available without antenna (RN42N) for applications that require an external antenna. The RN42N is form, function, and pin compatible with the RN42. Other configurations include: Apple-compatible firmware (RN42APL-I/RM), HCI mode (RN42HCI-I/RM), HID mode (RN42HID-I/RM), USB mode (RN42U-I/RM), and socket module (RN42SM-I/RM).
