The RN42-KB is a small form factor, low power, highly economic Bluetooth radio for OEM’s adding wireless capability to their products. The RN42-KB supports multiple interface protocols, is simple to design in and fully certified, making it a complete embedded Bluetooth solution. With its high performance on chip antenna and support for Bluetooth® Enhanced Data Rate (EDR), the RN42 delivers up to 3 Mbps data rate for distances up to about 30 feet. Designers can easily customize their application using up to 8Mbits of flash memory. The RN42 Supports 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 RN42-KB is the perfect product for engineers wanting to add wireless capability to their product but don’t want to spend significant time and money developing Bluetooth specific hardware and software.
