Voice-operated remote controls and smart home systems like Google Home and Amazon Echo are growing rapidly in popularity. To be successful, these devices need to deliver high-quality voice transmission in an attractive system at the right price point. The SmartBond™ Voice RCU development kit helps manufacturers quickly and easily create cost-effective, highly robust, and differentiated voice remote controls for many applications.

The kit comprises a complete hardware and software design for voice-command and gesture-based remote controls. It is based on the SmartBond™ DA14585 – the smallest, lowest power, most integrated Bluetooth® low energy solution to date – with high processing power and generous memory size for system and user functions.

The implemented codec with adaptive bit rate control automatically adjusts the data rate (24-64 kbps) to ensure excellent voice pick-up quality under any type of air link conditions. The kit’s robust performance consistently delivers over 90% correct voice command recognition under all tested conditions

The kit supports integration with Google Voice and allows manufacturers to differentiate their products through features like the user interface ranging from simple buttons to a trackpad or "air mouse". Direct connection for digital microphones via the PDM/I2S interface means no external codec is required, reducing system cost.

The SmartBond™ Voice RCU development kit enables low-power products that can deliver impressive range and work from a single or dual cell battery. It provides a flexible route to a comprehensive range of market-leading products.
