Product details
Overview
DA14585VRCUDEVKT from Dialog Semiconductor is a complete hardware and software development kit for voice-command and gesture-based remote controls, built around the DA14585 Bluetooth 5.0 SoC, featuring IMA ADPCM codec (24–64 kbps adaptive bitrate), PDM/I2S digital microphone interface, and dual-cell alkaline battery operation for smart home voice remotes like those used with Google Home and Amazon Echo.
For engineers reviewing the DA14585VRCUDEVKT datasheet, DA14585VRCUDEVKT pinout, DA14585VRCUDEVKT application, or DA14585VRCUDEVKT equivalent, key selection criteria include Bluetooth 5.0 compliance, integrated PDM/I2S audio interface, adaptive 24–64 kbps voice codec, touchpad/slider UI support, and IR LED with RC5 protocol - all validated in a two-layer PCB reference design with integrated antenna.
Technical Context
The DA14585VRCUDEVKT implements a production-ready reference design centered on the DA14585 SoC, which integrates ARM Cortex-M0+, BLE 5.0 radio, 128 kB RAM, and dedicated audio peripherals. It uses IMA ADPCM encoding with real-time adaptive bitrate control (24–64 kbps) to maintain >90% voice command recognition accuracy across variable RF conditions.
Audio path includes direct PDM/I2S digital microphone input with integrated sample rate converter, eliminating external codecs; gesture support is enabled via optional Hillcrest library integration; IR transmission uses RC5 protocol with onboard LED driver and debug header for firmware validation.

FAQ
What is the DA14585VRCUDEVKT used for?
The DA14585VRCUDEVKT is a complete development kit for voice-command remote controls targeting smart home ecosystems like Google Home and Amazon Echo. It provides validated hardware, IMA ADPCM voice codec firmware, Android app support, and modular UI options - enabling rapid prototyping and production of Bluetooth 5.0–enabled remotes with PDM/I2S microphone interface and RC5 IR output. The DA14585VRCUDEVKT includes all necessary firmware and reference schematics.
Does the DA14585VRCUDEVKT support digital microphones?
Yes, the DA14585VRCUDEVKT supports digital microphones directly via its PDM/I2S interface with integrated sample rate converter - eliminating the need for an external audio codec. This capability is implemented on the DA14585 SoC within the DA14585VRCUDEVKT reference design and verified with both PDM and I2S microphone types. The DA14585VRCUDEVKT documentation confirms full digital audio path integration.
What voice recognition performance does the DA14585VRCUDEVKT deliver?
The DA14585VRCUDEVKT achieves over 90% correct voice command recognition across tested RF conditions, enabled by its adaptive IMA ADPCM codec operating at 24–64 kbps and large internal audio buffers. Recognition leverages Google Voice Engine via the included Android app, supporting multi-language keyword detection and cloud-based search. This performance is measured and documented for the DA14585VRCUDEVKT reference platform.
Can the DA14585VRCUDEVKT be used for gesture control?
Yes, the DA14585VRCUDEVKT supports gesture control through optional integration of the Hillcrest Labs motion library, which runs on the DA14585 SoC. Gesture functionality requires separate license acquisition and firmware integration - it is not preloaded but is fully supported in the DA14585VRCUDEVKT hardware and software architecture per Dialog's official documentation.
What power source does the DA14585VRCUDEVKT use?
The DA14585VRCUDEVKT operates from two alkaline AA or AAA batteries, leveraging the ultra-low-power architecture of the DA14585 SoC to enable extended battery life in voice-activated remote applications. Its two-layer PCB includes optimized power routing and sleep-state management - all validated in the shipped DA14585VRCUDEVKT evaluation configuration.
