The RN-42 from Roving Networks is functionally 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 configuration. The RN-42 uses only 26uA 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. For applications that require an external antenna the RN-42 is also available in a package without antenna.

Roving Networks can also provide an evaluation board (RN-42-SM), a through hole, low power and highly flexible Bluetooth socket module. This socket module is the perfect method for adding Bluetooth wireless capability to existing products without redesign, saving significant time and money.
