Level Up Your Audio and AI Projects with the Balletto Wireless Microcontroller from Alif

Tucked into the bustling crowd at Embedded World 2025, Alif Semiconductor had a quiet but powerful story to tell—through Bluetooth. Their new Balletto wireless microcontroller isn’t just whispering sweet nothings to your headphones—it’s packing neural processing, BLE 5.3, and machine learning muscle into a single chip designed for next-gen wearables and hearables.

And yes, you can evaluate it today—no secrets, no silence.

Meet the Balletto MCU: Tiny Form, Big Ambitions

The Balletto family of MCUs is built for modern embedded designers who want to do more with less: less power, less space, less complexity. Think Bluetooth Low Energy (BLE), built-in neural processing for edge AI, and a robust development ecosystem that lets you get hands-on fast.

At the heart of it is Alif’s B1 chip, but for evaluation purposes, the real hero is the DKB1 development kit. Available now, this board lets engineers jump straight into testing real-world applications—be it audio streaming, machine learning, or both.

Showcasing Auracast: Broadcast Audio Without Limits

The demo at Embedded World featured a very slick application of the Balletto wireless microcontroller: Auracast, Bluetooth SIG’s latest high-bitrate audio broadcast standard. With Auracast, a single device can stream audio to multiple endpoints simultaneously—ideal for smart speakers, shared headphone use, or even public audio systems.

All of this was running live on Alif’s dev board, making it crystal clear: Balletto is more than just another wireless MCU.

Target Applications: Hearables, Wearables, and Beyond

So who should be paying attention?

• Smart headphones and hearing aids that require real-time audio processing
• Battery-powered wearables needing AI acceleration without draining the juice
• Edge AI devices where BLE and compact design are non-negotiable

If your project ticks any of those boxes, the Balletto wireless microcontroller might be your perfect fit.

Get Started: Plug, Play, and Prototype

Alif’s DKB1 development board is your fast track to testing the Balletto MCU. Plug it in, start evaluating wireless performance, AI capabilities, and audio streaming, and see how it behaves in your exact environment. No guesswork, no waiting.

As Alex from Alif said at the booth, “Balletto levels up your application.” And with tools like this, levelling up just got a whole lot easier.
