Computer systems with built-in Bluetooth Low Energy (BLE) support now have two new appliances to complete the wireless browsing experience. Designed to complement most desktop computers, laptops, tablets and set top boxes, the nRF51 wireless keyboard and nRF51 wireless mouse come with bluetooth HID over GATT compliance.
The nRF51 wireless keyboard set includes the RF mode switch and an accompanying USB receiver dongle running 2.4GHz Gazell protocol that will make it compatible with computer systems without BLE support. It is also rechargeable and features an easily modifiable key matrix and Microsoft media center keys.
The nRF51 wireless mouse set can be switched to Nordic 2.4GHz Gazell mode and connected to systems without BLE capabilities through the USB receiver dongle. Other features include the device information function that feeds specific information such as VID/PID and battery service that provides instant battery levels. The wireless mouse comes equipped with an optical mouse sensor, scroll wheel and six mouse buttons — left, middle, right, forward, back and DPI.
