Summary of Arduino Nicla Voice launches at CES 2023
Arduino launched the Nicla Voice at CES 2023, an ultra-low-power board featuring a Syntiant NDP120 Neural Decision processor for on-device AI audio tasks. It integrates a microphone, 6-axis motion sensor, and magnetometer with Bluetooth Low Energy. Compatible with Portenta and MKR hardware, it enables always-on voice recognition and predictive maintenance in a compact, battery-powered design.
Parts used in the Arduino Nicla Voice:
- Syntiant NDP120 Neural Decision Processor
- Microphone
- Smart 6-axis motion sensor
- Magnetometer
- Bluetooth Low Energy connectivity module
- Battery power source
The official Arduino development team have this week at CES 2023 launch their latest creation in the form of the Arduino Pro Nicla Voice. Specifically created to provide developers and users with onboard Bluetooth Low Energy connectivity and a board that is compatible with existing Nicla, Portenta, and MKR hardware. The tiny Nicla Voice Arduino board is equipped with a full set of sensors in the form of a microphone, smart 6-axis motion sensor and magnetometer.

Nicla Voice is capable of running audio inputs through the powerful Syntiant NDP120 Neural Decision processor, which mimics human neural pathways to run multiple AI algorithms and automate complex tasks. In other words, it hears different events and keywords simultaneously, and is capable of understanding and learning what sounds mean. The board is also small enough to be powered by a battery removing the need for powerlines switches or interfaces to activate the system.
