Bluetooth OEM Module (HCI over USB)	Product description:
	The RN-42-U With the HCI firmware is function, form and pin compatible with the RN-41. The primary difference between the RN-42-U and RN-41 is that the RN-42-U is a Class 2 device meaning its range is about 50 feet (15.24M) to 60 feet (18.29M) and correspondingly the power consumption is reduced. The RN-42-U is perfect for short range, battery powered applications. The RN-42-U 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. Supporting multiple Bluetooth profiles such as SPP and HID and simple UART hardware interface, it is simple to integrate into an embedded system or simply connect to an existing device. The RN-42-H is FCC and Bluetooth SIG certified making it a complete embedded Bluetooth solution. The RN-42-U is the perfect product for engineers adding Bluetooth capability to their product without spending significant time and money developing Bluetooth specific hardware and software.
