A wireless keyboard is what you need to get a full-effect of a cable-free desk allowing you to type wherever you like. Keyboard enthusiasts and power-writers can even use it to make their smartphones and tablets work more like a PC.
If you want to improve your typing experience, here’s how you can design a full-featured wireless keyboard for your smartphone, tablet or laptop using ready-to-use reference designs from the industry. These designs are feature-rich with low-power consumption, special function keys, and support for leading operating systems. Each design is discussed with all supporting documents including design files, BOM, test data, and user guides. Take a look!
- BLE Keyboard For Smartphones: TI offers a perfect Bluetooth keyboard for your smartphone or tablet which supports up to 128 keys and consumes an average 3 mW power using Bluetooth Low Energy technology to work for long periods of time. The keyboard can be paired with any host whose operating system supports a BLE-enabled keyboard like Windows 8.1 c. The matrix key-scan and power management functions are done by a power-optimised SoC solution combining a RF transceiver and MCU on a single chip to save space. The design includes schematics, testing and design files to build the system. More on this Reference Design
- Wireless Multimedia Keyboard and Mouse: Freescale offers a reference design to implement a complete system consisting of a wireless keyboard, a wireless mouse and a USB receiver (dongle) able to work at distances of 10 to 20 meters. The design centers on a MC68HC908LK24 MCU. A special design PCB differential loop antenna serves the purpose of a low cost, small form factor, and high directivity antenna to fit the design’s cost and size. Operating systems supported are Windows 98, Windows 200 and Windows XP. More on this Reference Design
