The Arduino crew has formally launched the subsequent entry within the compact Nicla improvement board household, this time specializing in tinyML voice processing on the edge with an built-in Syntiant Neural Resolution Processor (NDP): the Arduino Nicla Voice.
“With Nicla Voice’s ready-to-use mixture of sensors and processing energy,,” the Arduino crew says of its newest launch, “you may prototype and develop new options that leverage voice detection and voice recognition, or interpret another audio enter – from machines that want upkeep to water dripping, and from glass breaking to alarms that should get by means of headphones’ noise-canceling options. We will’t wait to listen to what you’ll create with it!”

Constructed within the smallest official Arduino type issue, which launched with the Bosch-partnered Nicla Sense ME in September 2021 and was adopted by the Nicla Imaginative and prescient in March final 12 months, the Arduino Nicla Voice is constructed round a Nordic nRF52832 system-on-chip with a single Arm Cortex-M4 microcontroller core operating at as much as 64MHz, 64kB of static RAM (SRAM), 512kB of on-chip flash plus 16MB SPI flash for extra storage, and a Bluetooth Low Power (BLE) radio for wi-fi connectivity.
The board additionally consists of built-in sensors, beginning with — unsurprisingly, given the gadget’s concentrate on edge-AI voice processing — an Infineon XENSIV IM69D130 MEMS microphone. Elsewhere is a Bosch BMI270 ultra-low-power six-axis inertial measurement unit (IMU) with built-in gesture, context, and exercise recognition plus step counting and a Bosch BMM150 three-axis magnetometer.
It is the board’s coprocessor that is of probably the most curiosity, nonetheless: the Nicla Voice is the primary Arduino to come back geared up with a Neural Resolution Processor (NDP) from Syntiant, designed to supply high-performance on-device machine studying with out excessive energy draw. The event board makes use of Syntiant’s NDP120, which launched in early 2021 as the corporate’s first to be primarily based on the second-generation Syntiant Core 2 tensor processor structure — and which delivers, the corporate claims, a twenty-fivefold efficiency enhance over its first-generation resolution processor components.
The NDP120 consists of help for as much as seven audio streams, I2S and TDM audio output help, its personal devoted Arm Cortex-M0 microcontroller, and 48kB of devoted SRAM — completely separate to the 64kB SRAM out there on the board’s main microcontroller. “We took years of actual world, low-power edge deep studying expertise to develop this structure right into a scalable design optimized to deliver neural processing to energy constrained deployments,” Kurt Busch, Syntiant’s chief govt, claimed on the time.

As with earlier Nicla boards, the Arduino Nicla Voice options castellated pins for breadboard or surface-mount set up, with a complete of two analog to digital converter (ADC) pins, an SPI bus, an I2C bus introduced out to a five-pin ESLOV connector, and a single UART. A ZIF connector permits for using an exterior microphone, whereas the enter/output voltage is switchable in software program from 1.8V to three.3V.
Extra data on the Arduino Nicla Voice is on the market on the Arduino Professional website. The board is listed on the Arduino Retailer for $82, with events requested to subscribe to a ready listing to position their order.
