DESCRIPTION
The RN-42 is form, function, and pin compatible with the RN-41. The primary difference between the RN-42 and RN-41 is that the RN-42 is a Class 2 device, meaning its range is about 50 to 60 feet and correspondingly the power consumption is reduced.
The RN-42 is perfect for short range, battery powered applications and by default is ready to use in the SPP (Serial Port Profile) configuration. The RN-42 uses only 26 uA in sleep mode while still being discoverable and connectable. Multiple user-configurable power modes allow the user to dial in the lowest power profile for a given application.
With support for multiple Bluetooth profiles such as SPP and HID, and a simple UART hardware interface, it is simple to both integrate into an embedded system or connect to an existing device. The RN-42 is FCC and Bluetooth SIG certified making it a complete embedded Bluetooth solution.
The RN-42 also comes in a package with no antenna (RN-42-N). Useful when the application requires an external antenna, the RN-42-N is shorter in length and has RF pads to route the antenna signal.
