The RN42 is a small form factor, low power, Class 2 Bluetooth radio for designers who want to add wireless capability to their products. The RN42 supports multiple interface protocols, is simple to design in, and is fully certified, making it a complete embedded Bluetooth solution. The RN42 is functionally compatible with the RN41. With its high-performance PCB trace antenna and support for Bluetooth EDR, the RN42 delivers up to 3 Mbps data rate for distances up to 20 meters.

The RN42 is available without antenna (RN42N). This is useful when the application requires an external antenna. The RN42N is form, function, and pin compatible with the RN42.

Note:  The Bluetooth SIG has deprecated Bluetooth 2.1 specification as of January 28, 2019. New designs with the RN42 will be unaffected. New designs with the RN42N will be affected. The Bluetooth SIG has also set the withdrawal date as July 1, 2020. Once the specification has been withdrawn, Bluetooth SIG will not qualify any new designs. *Existing designs are unaffected* Check out the Bluetooth SIG site for additional details HERE.

Firmware version 6.30 is the latest production firmware version available for the standard RN42.  To receive the latest firmware version 6.30, please order part number RN42-I/RM630

Firmware version 5.50 is the latest production firmware version available for the RN42APL.  To receive the latest firmware version 5.50, please order part number RN42APL-I/RM550
